I started with one rule.
Rule 1) "Girls like sparklies."
I want to instill in my sons some sense of what women are about. Particularly since my sons are not growing up with sisters I felt this was important. After the first rule and as my boys grow, I find there are many more "rules" that would be helpful. Hopefully if I ingrain these rules into my boys, I will end up with some very lucky daughters-in-law.
2) "Girls like when you close the toilet seat."
3) "Girls dislike spitting."
4) "Girls like chivalry."
5) "Girls dislike boys who hit."
6) "Girls like when you listen."
