I have several ideas, but many of these must be discussed via PM
1. All nighter and hit in the morning.
2. If you aren't going to marry her, skip PROM
Okay okay that's a little harsh (maybe that's why I'm not married yet). I skipped PROM for a playoff baseball game and a concert... there's no way prom could have been better..
3. Tell here you'll go to PROM if she goes hunting[8D]
