now this was my rule when I was once on the dating scene. Here goes.
1. Don't come over to my apartment empty handed. Hell bring groceries, a bottle of wine, or a blockbuster video. If they didn't do this....I politely did this. 
.
2. Don't come calling me at 2am saying "what you doing" when I haven't heard from you all day/and or days.
3. Whatever you do in the beginning (good) you had better keep it up!!!!!!!!!!!
