Of people

I've found it hard to understand some people's unpredictable behavior..sometimes they are seem to be a happy-go-lucky person while at times as moody and oversensitive creatures..Some expect others to care about them like five-year-old kid but they themselves are egocentric and relatively opportunist..take things for granted..Come on,be matured..I don't think I need to explain in details what,how,why you should do this and that every time bcoz I believe that at this age we are supposed to be sensitive (not the annoying sensitive one) enough to 'read any situation that could be improved' and then react.. cheers :)
