Double face

From time to time, the more I get mixed with my classmates,  I knew them more...
in other words,  I discovered what kind of human they are...
bad? sometimes
good? depends on their feelings. ..or depends on on your look, whether u are handsome/pretty or ugly.
They might treated you like close friends but behind you they might plotting something. ..or backstabbing
Well! I don't really want to care bout it
Do what I suppose to do
