Lost a day

It's Thursday.......

I just found out, I have been going about my business convinced that it is Wednesday!

So where did I lose a day, I checked down the back of the sofa but it isn't there! I didn't leave it in my pockets and wash it... I have no idea what has happened.

I can't even recall what I apparently did on this lost day but my blogs show that I was active.

Have you ever lost a day like this?
