If she's a great Ultimate Frisbee player, then there's not much you can do other than display quiet competence and a sense of fair play and hope for the best. But, if she's still learning or is not as skilled as some of the others ...
- If she's on your team, throw her the disc whenever she has a decent chance. Don't always go deep to the star player.
- Compliment her on a good catch, throw, or a great try.
- Never show anger at a flubbed play.
- If she's on your team, smile at her when doing high-fives after a point.
- If she's on your team, walk back with her during Losers walk.
- Always know where she is on the field.
- Make small talk when you're both subbed off and during Losers walk.
- If she's on the other team, make light of the ultra-competitive team member (there's always one).
- Tell her you enjoyed playing with/against her
- Never turn down the after-game run for beer, even if you don't drink.
