So today I had to supply my wedding date for some financial forms and I went to enter the date 8th September 1990. I paused for a moment and suddenly panicked and feared that date was wrong.
The more I focused on it the more remote it became and suddenly that date just looked wrong and I wasn't sure any more.
So I had to look it up, first time in 20 years...at least it was correct in the end. I hope this is normal :-)
