Expose yourself, accept the other's ugliest, share productive experiences. Candlelit dinners and wine won't do the trick. Unless I'm wrong.
Be you. If you enjoy their company all you can do is hope they enjoy yours. Accept the other person. Once you're close to someone, they enjoy being with you. They'll most likely get the warm feeling you want them to.
Well, it's just great to think about the others more than you think about yourself. Inspire the person you want to make happy. And be positve!!!
