Ah the friend zone. My experinces have not been so nice. I've had long term friends that I dated and now hate. If a guy moves into the friend zone, he's not there for good. Just until he looses the girlfriend. I'm just kidding! Seriously, guy friends aren't that bad. I've known a set (male and female) that were friends off an on for years and when they were both out of a relationship they would "date" each other. Even had sex, but it wasn't a "relationship" (at least that is what they say) and continue to be friends even while dating others. Everybody knows they are an awsome couple, except for them.

Whoa, but I'm rambling.

Anyway, the friend zone is not a bad place to be. It can transition one way or another. Love to friend, Friend to lover. But like Bianca said, look for the signs she listed to see if she is interested. ALWAYS offer a hug, patting her hand or arm is good, and I know this sounds weird, but grooming her. If she has lint on her or a stray hair, maybe asking to remove it at first (if the tocuhing trust has not been fully accepted) like "oh, you got a hair there, let me get that for you" it shows to me that you care enough to make sure I look good in public or even for you.

Yes we are that retarded.

Know this simple fact about woman. We read into EVERYTHING. A late phone call means he doesn't care. A bundle of flowers shows he does care. Three or more roses is love (in any color except yellow). If you are interested in a woman, one red rose speaks volumes. When you get a phone number, it is customary NOT to call the following day. This is acceptable. Sundays don't really count. It is sort of like a time out day. But do not let it go past three days, otherwise, she'll think you are not intersested (one guy waited a week and called me on a friday for a date that night. No! Bad! That is a good example of what you DON'T do).

...anything else?
