no point whining about it

Câline: Just imagine you're walking along and you get hit by a bicycle. You're injured. All you can do is wait for your injuries to heal. No point whining about it.

Nicolas: Aren't you a little angry at the cyclist?

Câline: What for? It won't make your injuries heal quicker. It wasn't the cyclist's fault. He didn't do it on purpose.

Nicolas: True. But some might blame him for not being careful enough.

Câline: But it takes experience to be careful. You can't blame someone from lacking experience.

Nicolas: That's exactly right. That's very well said.
