Do you have those times? Do you have those hard times that you don't want to remember  at all, but it comes back whenever you meet or hear of someone or something? 
I've been living under a bad atmosphere of people and things for two years, I just can't face  people  there again or even hear of them. They make me feel like a loser which I won't  admit.

Stay Away From the Persons Making You Negative There's an acquaintance always telling me negative things, which makes me very sick. And the truth is he holds a job as a teacher in an university, envied by many people supposedly. However, he just can't look on the bright side, all he saw are such things like low salary, highly housing price. What's worse, he told me to give up what I am doing and gave me one reason. Whatever I try, I'll be like him with no bright future. Of course I won't listen to him because even he and I share the same research field, there are still many other things deciding the future. In other words, every one has his own destiny. All I can do are working hard and staying away from him who may drag me into a deep hole.

What does " the radio is stuffed" mean?

What do you ususally do on weekends? Basically I like to travel a little bit, discovering something fun,  but sometimes I just don't know what to do and sit there with my head blank. 

Do you like cats? I don't like their eyes,  kind of creepy.<img alt="" src="http://www.italki.com/fckeditor/editor/images/smiley/msn/regular_smile.gif" /> 

Self-confidence Makes Difference Yesterday night I messaged a classmate and we talked a little, we happened to refer to each other's future. I said "what will I be in the future?". He made an answer for me "To be a xx", "Can I?" , "Yes, you can if only you have confidence and work hard". Usually, I am not a person full of self-confidence, but I know he is. You can tell from an experience we both engaged in. Well, he and I were in the same lab before, and one year ago right after graduation, we decided to invite our supervisors to dinner to thank their dedication to tutoring us. His girlfriend recommended a restaurant which we hadn't been there before, so we should first find that place and make reservation. We went to the road where the restaurant located, but we went back and forth for several times, and still couldn't find it. My reaction was "How could I be so stupid that I couldn't even find a restaurant, while he acted conversely, like " The restaurant should be moved to another place." At last we found the place, it turned out we both didn't keep eyes open enough, because it was right there. So I always wonder that if I had enough self-confidence as he, how far can I go? But one thing for sure, farther than where I am now. I am trying to be more confident.

what does "go off like a frog in a sock“ mean? It seems like a phrase used in Australia, I came across it in a TV script. Thanks for answering.
