I have only been hit on once in my entire life and it was awkward.
I was waiting for a train home at a railway station, sitting on a bench reading. Suddenly this black fellow came over and asked in English if he could sit next to me, I said yes (of course, it's not like I own the bloody seats). The man sat and started talking to me about nothing particularly suspicious: he said he had come from Italy to see his brother, was waiting for a train, etc. I thought he was just bored and was used to having conversations with strangers in Italy, I dunno. But before I knew it the conversation shifted from me telling the approximate direction where I had come from and where I was going to him wanting to know the exact place where I lived and whether he'd have a chance of coming to my place after he'd seen his brother.
Good lord.
First of all, I'm ugly. I'm not even remotely attractive unless you have some sort of peculiar fetish. I'm fat, I have small breasts, I don't wear makeup, I prefer loose gender-neutral clothing, I have a sort of manly jaw and wide shoulders, and my skin is pretty ugly too. And if that's not enough, I don't think there are people who interpret my body language as open or inviting, I'm a bloody asexual who doesn't like physical contact. I tried to politely inform him of these facts, but he went "No no no, you are pretty! And I like inner beauty better anyway." and completely skipped the "Sorry man, it's not you, I'm just not looking for a boyfriend" part.
The guy was pretty pathetic, he seemed desperate. Even though I eventually hinted that I actually meant that I'm also "ugly on the inside" and that I may or may not actually be a psychopath, he kept on. All this to scare him off, and it didn't work! Fortunately, after he tried to convince me that I have pretty eyes and lovely curves (which he couldn't have possibly seen from under my heavy winter coat), he had to go to the loo. But he said that I'd have to wait for him so we could exchange numbers.
Nothing personal against this guy, but hell, what a desperate sucker. As soon as he went to the bathroom corner, I ran off going "Pfffffth!" and digging for my mobile so I could call my friend. We both laughed and we still laugh at this incident. Whether this fellow was for real or had a strange sense of humour, he really made my day.
