Anyone seen this mitten?

For some reason, around this time of year, one tends to find a lot of lost mittens and gloves. Maybe it's because the weather is warming up and people walk along clutching them rather than wearing them. Perhaps they drop one as they are walking along. I know that I have been spotting the odd lost glove or mitten on my way to work. Two just last week, and one the week before. Whenever I come across them I pick them up and try to find a post to stick them on in the hopes they'll be noticed by their owners. I have several odd mittens here at home myself. Their mates are missing but I keep them, hoping that at some point I'll find the one that's gone astray.
