this happened about 20 years ago.

i was working as a trainee programmer and general support for a small telesales team of around 12-15 people.
a new girl came to join the telesales team and was shown around and introduced to everyone, including me.

i was bowled over - she was stunning, and i made a point of saying as such to one of the girls in the row opposite my desk.

"oh, that's just mary [not mary]. i went to school with her; i'll set you up."

...and she did.

we went to the pub and had a drink, got on well and arranged to meet up the following friday.

now, the chap who was training me had a rent-free flat that came as part of his employment deal. he'd only work up to thursday's and then he'd go home for the weekend, and he'd leave the keys to the flat with me.

mary and i met up and after a fair few drinks, we ended up back at the flat. another friend was there and she was on her way out, due to return much later in the evening.

mary and i started getting down to it on the sofa, and around 10pm, she said, "i don't think i'm likely to be able to get a taxi home at this time of night..."

being the chivalrous type, i told her that being only 10pm on a friday getting a cab would be easy, and in fact, there was a taxi rank at the bottom of the block of flats.

i went downstairs, ordered her a cab, went back up in the lift and said, "i got you a cab; he says he can take you right now."

...and so, off she went.

i returned to the flat and started watching tv while laying on the sofa. a while later, my friend returned to the flat and said, "oh...did it not go well with mary then?"

me: "eh? what do you mean?"

friend:"well, she's gone. when i was here earlier she had an overnight bag on her shoulder. she was obviously looking to stay here the night."

...and that's when it dawned on me what a complete twat i'd been.

i spoke to her a couple of days later and asked her if she would like to join me and a few friends at a local restaurant.
she declined.
