When you get to a restaurant together, watch carefully how your date behaves, because the way he deals with the server will indicate how he will deal with you someday. If he is making a sweet impression on you, but is demanding, neglectful, or disrespectful toward the server, this is a big clue that the fellow is probably impolite when dealing with most people.
If your server is an attractive woman, you are in the best seat in the house to watch for character clues. Does your man eye her up and down, as if she was the dessert, instead of paying attention to you? Is he bossy, or flirtatious with her, and does he leave an appropriate tip, for good service rendered during the meal? The writing is on the wall, and all you have to do is jot down a few notes to figure out the whole biographical sketch of a guy in this kind of situation.

You may, in fact, discover that reading him is better than curling up with a good book when you crawl into bed at night.
Fortunately, good signs are usually just as easy to read. By observing the peripheral clues to the inner personality and character of your date, you may discover that he is generous, calm and controlled, assertive without being rude, respectful and flattering without being a hopeless flirt, and that he has compassion for other people and a genuine attraction to you in particular.
You may, in fact, discover that reading him is better than curling up with a good book when you crawl into bed at night. But we will leave that final chapter of the twisting plot of your new romance novel for you to write (or co-write, as the case may be!).
