from vs by I had/got  my hair cut from/by my hairdresser.   Can I use the prepositions interchangeably in this case? 

'in the moment' in a sentence without the preposition 'in' possible?

The author of this sentence chose to leave out the preposition 'in' before the phrase 'in the moment' which kind of throws me off. I can't make friends with it.Is there are rule behind it? 

I always dreamed that I would own an amazing animal like this someday; a huge teddy bear that can wrestle playfully with children one moment and in the next, snap to attention at the owner's command and be the protector

The word "after" + past tense

Can I use the the past participle to state a situation will be happening AFTER I did something in the future?

Example :

After I moved  I'll be looking for a job

The first thing I'm going to do after I moved is looking for a new job

After I moved, I'm going to look for a job 

English conversations Last night I'd my first conversation in English on Skype. I was pretty nervous and also shy to speak with my accent. I also got scared because I knew I would lose my vocabulary and forget everything I've learned so far. And it happened! It was an awkwardly silence and my exchange partner tried to break through by telling me about her last presentation at work. I'd a hard time understanding specific, work related , details not only because of a bad sound quality on Skype. I think my level of listening comprehensions is very low although I can understand the most English videos on Youtube. It's a different story to understand someone in a conversation compared to watching a movie were you can go back and forth all the time to listen to specific parts more often. Also it is very hard to speak without thinking to much about pronunciation, grammar, and sentence structure. It took my like 10 min. to write this simple note book entry right now. If I'd spoken to somebody I'd never said it the same way.

Past forms I just did a Cambridge online language test to find out which level in English I have. I reached only 20 of 25 points. There is a specific case I don't understand : They asked me to choose a word out of 4 to put in the blank field. 13. My father ...... his new car for two weeks now. 1.has had 2.has 3.is having 4.had I did choose to put " is having" because it sounded natural to me. But the right answer is "has had". I absolutely can't agree to that because "has had" refers to the point that he don't has the car anymore. But it's saying "two weeks now" which implies that he is still having his car. So for me it would be more natural to say something like " My father is having his car for two weeks now" or something like " My father had his car fro two weeks, but he sold it two days ago" or " I really don't get the grammar and it's freaking me out right now. Why are they using "has had" and do I even have to use "Has had" "Have had" in general? Aren't there any other ways to describe something you did in the past which is still happening? "Like I've been watching TV the whole night" " I've been working for this company since 1994" or something like that. You guys get what I mean, don't you? :)

It's all about... It's all about you It's all about me What is the subject in this sentence? I asked someone " It's all about that ...." and she was asking me " What is all about that...." . I am really confused because I thought the subject is on the end of this phrase like " It's all about that car" , so it's the car. Why would ask someone in this case " What is all about that car ? " ? Maybe I misunderstand the meaning of the phrase. In the first two cases it refers to the person, e.g. "you" "me" . So why is "It" the subject, when we already know it's about "you" or "me" ?

I let you down, i'm letting go... This is a part of a song I like and I try to figure out what it means. The dictionary is giving me a hard time... The German translations make no sense at all!

Etwas hinter sich lassen in English ? Beispiel : Ich habe mein altes Leben für dich hinter mir gelassen! Wie würde das in Englisch aussehen?

Last week, an on-the-street video of a woman walking around..... "Last week, an on-the-street video of a woman walking around New York and getting catcalled by men went viral. In the video, the woman was catcalled more than 100 times in 10 hours, and seemingly couldn’t walk a single block without someone making a pass at her. Model Pranksters has just released a response video of its own. In this instance, an attractive, muscular man in a white t-shirt walks around the streets of NYC for three hours. The looks and responses he receives from both men and women are similar to the harassment the original woman received in her video. Unfortunately, it seems like no one is safe from harassment on the streets, especially in a crowded city. " What does "making a pass on her" mean in this case? I also can't find a translation for "viral" . Is it like a synonym or something?
