there's no rule.

Remember when we were younger and people always say
"be good towards others and they will treat you good"
Well.tell me,has that line helped you all this while?
i have learned this through the hard way.
I dont know about y'all but as for me,
People will always take what they think belong to them
and they're gonna take it anyway,hard or easy way.
So screw it.Don't believe that if you do good,people will surely do you good.
If the line was to be true,then the words
"backstabber," "lies", "betrayed" wont ever exist.
My point is,do whatever pleases you.
