Can someone tell me?
Why do people dont thank people who answered their wishes.
When they want something,
They will say
If this this this goes smoothly.
I will do this this this
But when "this this this" really went smoothly
How many really sincerly thank before?
How many really fulfil what they said?
Can someone tell me why?
人都是忘恩负义的吗?
为什么?
