Hahahaha...tinkle means something very different where I'm from! I couldn't think of any Christmas song that had anything to do with relieving oneself! ;)
Haha - I only saw the instructions about the initials after I'd finished! Quite tight typing all these on a phone, especially as many words aren't going to be suggested by predictive text...
I didn't know the song and typed mama. And wasn't aware we could use initials. That must be when I ran out of time.. no time to read the last one and was about to type the 2nd before last. And hadn't really stopped to think.
Could you accept Mummy for Mommy please.
People speak differently. Is that seriously such a problem for you?
I'm British. It was written by a British lyricist. It's mommy.
HTH :)
