I'm going to ditch my prom date at the door
Why on earth would you do something so mean to your prom date?
I think she's ugly and smells bad.
She looks the same as she did when you asked her to prom. You should not ditch your date because of that, it is hurtful!
What do you know? If I want to ditch her, I can do it.
If you think your date is ugly and smelly, you should not have asked her (or agreed to go) in the first place. Prom is really important to some people, and it would be cruel to leave her with those memories. You should go and do your best to have a good time.
