A few years ago, a friend of my cousin became a licensed dentist here in Sweden. My cousin had to remove a tooth and his friend gave him, I assume, a lower price because they're friends...

He removed a tooth alright, but the wrong one (on the wrong side). And apparently my cousin just assumed he worked on fixing something else, realising the mistake way too late.

I asked my cousin if he considered suing but he didn't want to do that because they're friends...

Weird situation.
