Boys and Girls

I am writing a list of things that boys think that that they can get away with but girls definately can't;

1. Ringing you more than once when you didn't answer the first time.
2. Talking about marriage on the first date.
3. Trying to get you pregnant.
4. Asking you if you can be their girlfriend on the second date.
5. Putting out on the first date.

Any further suggestions would be most welcome.
