Have you got my best side?

Had a photo group meeting this morning and all through the meeting a little long tailed tit kept coming and settling right outside the window (with it's chest feathers pressed right up against the glass), there are three windows in the room and it went to each of them many times. I did take a photo but it was with my compact and through dirty double glazing so it wasn't very good, but I just can't work out why it was doing it, nobody feeds it from there but apparently it has done it before. After the meeting I called in at the nearby country park, there were not many water birds about and I'm not surprised, it was absolutely freezing cold, so I just snapped this and left. I have played around with it a little to try to liven it up a bit and I think it's about the best I can do today.
