My madness

I was sitting at my desk at work today and a colleague came over to me and said "I'm not sure how to word this and I don't want to cause any offence but I think this is likely to be yours". It is of course mine and really since its usually pinned to my work lanyard (with others) I guess they could have been the one offended! I was just grateful for its return, I hadn't even noticed it had fallen off! I was also quite amused by his nervousness when returning it...
