Damn you Colin

I was in Glasgow at the weekend for a wedding. On Sunday we had a few hours to kill before heading to the airport for the flight home. Walking down the street we were handed a flyer for a craft market in a nearby venue. After looking at some shops, my wife and I decided to go there as she was on the lookout for some Christmas gifts for friends.
The entrance to the venue, a restaurant/bar, had some stalls that she was attracted by. After a quick look, I decided to check out the inside.
As I entered the building it was quite dark and an unusual venue at that. Prior to entering I did not realise that it was a bar - it looked like an old hall of some sort. Inside, it had a high vaulted ceiling and lots of banquette tables. It was not entirely clear where the craft stalls were.
I was looking around and getting my bearings when a lady at a table looked at me hopefully and asked: "Are you Colin?"
Rather too hastily I said that I wasn't and walked past her. Almost immediately it struck me that she was waiting for some sort of date, and that my response could be taken for the brush off. I'd arrived like a sneaky snake, caught a glimpse of her and thought she wasn't to my taste - too old, not pretty enough, boring looking. These weren't my thoughts about her, but they were now what I was thinking she was thinking.
I suppose I could have gone back and explained that I really wasn't Colin and that I was here with my wife (to my shame, I did actually make a bit of a show of her being with me when she eventually came into the building), but that would have been about making myself feel better.
I could have started talking to her and gave a better impression of myself. Even if I wasn't Colin, I was the sort of person who would speak to somebody on their own, nursing a coffee on a grey, rainy Sunday in Glasgow.
Instead, I probably made her feel worse about being on her own.
As we went to the balcony area where the craft stalls were, I noticed that she was shuttling out of the building on her own.
I don't know why I'm feeling guilty about this. It was Colin who was the no show.
