1. Don't EVER tell us to CALM DOWN when we're angry. We hate that, and it often makes the situation worse.

4. Don't give us commands like we're some kind of dog. We're your equal and should be treated as such.
5. Sure, you're the guy, so you can act like you're the stronger one... Whatever... But, don't EVER act like you're the head of the house. Relationships are to be an equal situation.

24. Don't forget to compliment us when we put on a cute outfit and spice up our look. It pisses us off when we spend all that time getting ready to not get a compliment from you.
25. When you know we're right, don't act like you know you're right. When you're wrong, it's better to admit it.
26. Don't treat us badly in front of friends just to show your manly-hood. Again, we're your EQUAL.
27. Don't cop a joke on us and embarrass us. It's NOT funny! Especially when we're surrounded by strangers or friends.
28. If we ask a question like, "Do I look fat in this dress?" Don't tell us a lie to save our feelings. Tell us the truth. But do it in a nice way. Not a mean way. This will show us that you're honest.
29. Don't forget to tell us you love us!
