Chance meeting(s) when leaving it to chance.

Fifteen years ago I met a girl in a nightclub in Central London, we talked for 10mins and she told me something that made her distinctive and an interesting character. Saw her once again a few weeks later but we never spoke. Ten years ago I was at a comedy pub in Greater London and there was a girl heckling the first act from the front row. During the break I was stood next to her and thought she seems an interesting character I ought to speak to her, but we never spoke. Nearly three years ago after breaking up with my ex I decided on new year eve that I would like to meet these two interesting characters again. But how, as I met one once but did not know her name or could not remember what she looked like , I never spoke to the other and could not remember what she looked like either. But I decided I would goto the nightclub again and goto comedy nights .... and leave it to chance/fate/whatever. But I didnt have the money to go out (newly single), until it got near valentines then I had an urge that I must go out. So I went to an anti-valentines night. The third person I met was a girl who I thought was an interesting character and thought yeah she'll be good as a new friend. So the next time I saw her at another singles event I asked if she fancied going to see a comedy night at the nightclub I intended to go back to. She then tells me the same story I'd heard from the girl 13 years before. It was the very same person. I'd decided to look for her, and met her the very first time I'd gone out. I was gobsmacked. I told her I'd met her before and repeated other things she'd told me. She was oddly amazed by the story. A few months later we were going past the comedy pub where I'd seen the other girl. And she starts to tell me about this time she was in there and hecked a comedy act. After a couple of more questions ... it turns out she was also the 2nd person I'd decided to look for. I just do not know how I to work out the chances of this. Bumping into these two people again has one set of chances. But to actualy decide that I was going to look for them both, and they are the same person and I met "them" the the first time I went out after deciding to look for them. Incalcuable I think. And no we never became a couple, we are not really suited. But I'm sure we'll be friends for a long time.
