['A friend of mine spent all night partying instead of staying home to study. He ended up failing an important exam!', 'That is no good.  I bet he regrets it!', 'I sure hope so! I warned him about going out drinking too often. Maybe this will teach him.']
I hope so that is frustrating.
Just found out my friend failed an important exam because he was out partying the night before and didn't get much sleep.
