If it makes you feel any better Muc I wouldn't project a false image of myself to get a girl to like me.
I agree with the whole letting her get to know you thing...but if a piece of network cable or a T-shirt turns her off then it would be a waste of effort for both of us to try.
If by some odd chance I ever do find "that special girl", she's going to have to put up with a lot weirder things than those...I can see myself getting her flowers if she likes that sort of thing, but I don't consider that a very personal gift...I would prefer something a little more personal...
Of course, taking my advice is probably a bad idea...I've never been on a date, and I doubt most girls would judge me as dateable. I've got lots of really close female friends, but I doubt any of them would call me dateable...and though I'm okay with that...but it's still a fact.
