How could I forget!

I forgot to clean my teeth too one day this last week. Like you, it was because my usual routine was interrupted, in my case by the earlier than expected arrival of 18 month old for a childminding session.
I suddenly realized that afternoon while stranded with my broken-down car (with dgd) waiting to be recovered. Realizing that your mouth doesn't taste fresh is bad enough, but it's even worse when you have over two and a half hours in a confined space to dwell on it!

Went to visit my daughter last week and realised ( when I looked in her mirror) that I hadn’t combed my hair!

No not just you.
I forget to turn taps/lights off.
Go back and check and sometimes I have done it.
Come to the conclusion as we get older we store too much info in our head to do or not do the normal things.

No, don't worry, not just you!

I often forget basic things, especially if distracted.

Wait for me Sunseeker! ???
