I'm going to let my drunk friend walk home alone while I stay out at the bar
Why would you let him walk home alone?
My friend needs to learn to live on his own sometimes. If he wants to be miserable and drunk, who am I to stop him
It's dangerous for your friend to just walk home alone while drunk. You shouldn't just abandon your friends like that.
Don't be a buzzkill just let him go.
All I'm saying is that something bad could happen to him. You should help him make sure he gets home safe.
