They..Why?

Last time,
'They' gave me alot of happiness...
'They' gave me alot of sadness...
'They' gave me alot of memorable story..

Now,
'They' become like devil...
'They' become like Don't know what to do..
'They' make me felt no mood when practice..

Why 'they' do like that to me or the others?
Why 'they' like to be strict but they was use wrong way?
Why 'They' Don't Listen our suggestion?
Why 'They' thinks that they're correct?
Why 'They' can't think what other 'members' thinking of?
Why 'They' can't disguss together what they gonna do?
Why 'They' meeting..Talk about the others Din talk about some problem?
