这是几岁的娃啊？我就跟孩子说，he’s an unreliable person. If you still want to have a playdate with him, then he’ll get here when he gets here. If you don’t like the wait, then don’t invite him over next time.

我觉得孩子应该学习change thing if you can, accept things if you cannot change it and don’t get upset over other people’s mistake
