What does this phrase mean?-"I get caught up". A foreign person emailed me that "Sorry about that, because I got caught up". I do not understand this phrase. Can you help me?

Can I say “my compositions always excelled in class”？ I am wondering whether this sentence"my compositions always excelled in class" is right. Can I use "compositions" as a subject before the word "excel"? If not, how can I express this in a right way? thank you!

Criticism of the Chinese movie Women Who Flirt Yesterday, I watched the latest movie Women Who Flirt with one of my friend. I guess the reason that she wanted to watch this movie with me was that she would like both of us to get educated by so superficial a movie,learning how to flirt with men.The theme of the movie is that only women who know how to flirt can eventually lead a happy life. How sad men are! Under such a stupid perspective, they create an art work without little art value.I was so surprised to imagine that in the modern society, men are still picture women as an auxiliary part of them.

People's judgement on us These days,I was upset for receiving some judgement from a friend. She told me that there was a lot of space for me to improve my expertise on my major.She also pointed out that I was not cut out for this field. I totally agree with the former judgement,but to the later one,I feel heartbroken.It was really a sincere comment and exactly because of which,frustration overwhelmed the gratefulness when hearing someone tell you the truth. "How silly you are!"Mom said surprisely."How do you know that it IS the truth?" "You should always be confident but humble,using your own brain to make decisions and judgement instead of letting other people to tell you what to do and what is right or not." Never be over-optimistic,never be self-diffident.Mom is always in possession of that wisdom.

We don't have bottomless time I have learnt a new English word recently——bottomless. It has different meanings,and people may be happy to see it in restaurants. But now,I really want to groan that I don't have bottomless time...(I don't know it is right or not to use the word in this way.) I like English,but I don't have that much time to learn it.I have my own major and I should start to formulate ideas for my graduation thesis.And there are still a lot of things to do... Time is so limited.How can we choose to do the right thing at the right time? Ok! Rise and Shine! It's never too late to start.Maybe what we should do is to see our time like a sponge.Squeeze it,and it will turn to be more.It's not the amount but the arrangement of time really counts. I'd like to share a poem with you.I read it in a novel written by Jack London,and its origial composer is Swinbure.I don't know who he is,because I can hardly understand foreign poems(I love Chinese classical poems the most).But I feel peaceful and calm when reading this piece of masterpiece. From too much love of living; From hope and fear set free; We thank with brief thanksgiving; Whatever gods may be; That no life lives forever; That dead men rise up never; That even the weariest river; Winds somewhere safe to sea. ------------ Life is hard,and time is not bottomless. Actually,we should thank for that.We will enjoy eternal peace in the future,and for now,just fighting~! (I am studying English from ESL,an American podcast programme,and podcast produced by BBC.They are very good!But They also makes me have the desire to use those slangs in an essay.Um......In an examination,I shouldn't use bottomless in my essay,should I?)
