i meet funny people

I think most of my friend was a joker.Whenever i have some time and i'm not in tired conditions,if i have any reference book with me i'll take the time even though 5 minutes to do some revision while waiting teacher entering the class.My jokers friend which are different school with me will ask "tomorrow exams is it?".And i will say "no and ask them is that they feel exciting on last minutes study is it?".One of my friend say "yes" without thinking any and follow with "revision on normal day is boring,while the time going to exams is fun".Or not if the one is my schoolmate they will ask "are you taking this particular subjects after this?".The same answer from me "no,just do some revision".
