But I Thought...

As I've told previously, we were having a soup day at work and I was going to bring pimento cheese sandwiches. Said event was to happen on Thursday so Ragged and I went to the grocery and I got a big ole tub of minner cheese and a loaf of bread and happily schlepped off to work yesterday. Well, soup day is next Thursday. I realized the mistake before anyone noticed, so when I left I sneaked back out to my car with my sandwiches makins. Is this a sign of getting older?
