One were both people feed off each other and are able to keep up fun and interesting conversations.
Were both people are dressed nicely and keep positive, cheeky and sexy. Were only one person pays for the date (not half and half! - is a deal breaker!), whoever doesn't pay anything on the first date can pay on the 2nd date.
You must be walked home by your date, well maybe not to your house but close enough to it.
Your date must offer to buy you a drink, or else!
If you want to dance, your date must also dance with you, even if he/she doesn't generally like to...
I'm sure there is more, but can't think off the top of my mind.
