Who's the Daddy?

Have good manners, number one. It shows you’re not a dummy. Don’t try to impress her with intelligence or to make her laugh too much. Treat her with respect……...

Treat others well and with respect... waiters, waitresses, grocers, other employed people who he deals with. 

Show her that you truly are interested in her, listen to her and be sincere to her feelings. 

Think about your best qualities and express them.  If you are interested in her, show it by listening to her, & don't flirt with other women while with her.  Be honest.  If you are truly a gentleman, be one. When talking with her, find out if you two have any common interest.  If you do talk about them.  Be relaxed. Don't judge yourself or her.  Good luck.
