Just had a knock at the door and I answered to a little girl of about 6. She looked really shy and uncomfortable and began to quietly sing at me.
I asked her where her Mum and Dad were because I couldn't see anyone and she pointed to a women standing about two houses down. She called out to her to 'sing Jingle Bells', which she did 
Anyway I asked her what she was collecting and she shrugged, I didn't have anything to hand so I said thank you and shut the door.
AIBU to think this is odd? I feel a bit mean now for not giving her anything and I know DH will say I was tight when I relay this story later
I just found the whole experience weird.
