More of a WWYD as another thread has got me thinking. Last year my kids (6 and 7) asked lots of questions about why Father Christmas seems to bring some kids more than others, I've also recently had a question about why the tooth fairy pays at different rates. Can I ask those of you who do the whole Father Christmas thing if you've come up with any good responses to these questions? My responses have been lame and not stood up to further scrutiny.
