I said yes I did know but it was very kind of her to be concerned and I would write myself a big note to make sure I remembered to do it.
It's nice to think that they take such a personal interest, isn't it?
Now I didn't want to let her down - imagine her disappointment if, come 1st February, she checked and my form wasn't in! - so this afternoon I sat down to do my accounts so accountant, aka Husband, could do the online bit for me.
It took me all of half an hour and the back of an envelope.
