The nice decent guys do not talk to tend to talk to me. I have gone out of my way to say hello to them and they just look at me and say nothing.
Wow, I'd never outright ignore ANYONE, let alone a beautiful woman. Now, I'm married as I said before, but let me turn this around a bit...
Say a guy wanted to talk a little, not really interested in a date or anything, maybe he thinks you're quite attractive. These days we're bombarded with messages at work that something as simple as a compliment can be 'harassment.' I am notoriously shy and HATE to say as much as hello without practically an engraved invitation to do so. How would you suggest to spark a conversation that wouldn't make you think 'this guy just likes my tits.'
I guess this kinda comes with my social ineptness. Women usually say I'm very sensitive and 'emotionally intelligent' but I have a huge problem with things as simple as making friends. :p
