Here's what I know...
(1) Men like happy, smiling women. If you can't smile, don't go.
(2) Men like you to ask questions about them but nothing too probing, just light and fun.
(3) Men like girls who laugh at their jokes, so even if your guy isn't really funny, throw in a giggle every now and again.
(4) Guys like girls to flirt with their eyes. Try giving him a long stare eye to eye, it will captivate him.
(5) Guys don't like a girl who have 11 changes to her food order. It's okay to order dressing on the side, but other than that, suck it up. If you don't, he might give you a draconian kick to the curb!
(6) Guys like girls who say thank you after they pay the bill or as they are walking out of the restaurant; they want to feel appreciated.
