When you can't remember what you think you forgot

At the weekend I learned that there'll be a concert of Cartoon Jazz on Saturday 7th March. A bell rang, faintly in my brain. Having checked diary, purse, dental and hairdresser appointments I was no wiser as to why the date of Saturday 7th seemed important. Staring intently at my diary today, I worked it out. Saturday 7th February (not March) will be B's birthday party. That 28 days in February thing confuses me every time, but never mind, we can go to the concert.

I did end up reminded that I still haven't organised her party. She wants to go to the cinema with friends. Cinemas don't seem to advertise Saturday children showings more than a week ahead.
