In college dating, things can come up at a moment's notice that lead to a girl canceling a date. Props to our protagonist, because he really couldn't have played it off any better than this. If you ever get canceled on, you need to:
1. Tell her you don't care (even though you do)
2. Act like you have other plans (you probably don't)
3. Never let her find out how devastated you are
It's the only way.
