Don't leave me

I just had a conversation with a friend and she decided she had to go. I tried to convince her not to, but to no avail.

Friend: I need to take a shower. I'll be back.
Me: I need to take an ax to someone's head. What's your point? I'm not doing mine!

Alas, she left me. I thought I had a pretty convincing argument. I guess not. Oh well.
