Why do men *never* listen?

So this morning, I rush around like usual but I had the added bonus of making sure the kids costumes are in bags to take to the in laws house(where the kids go every other week). My daughter was really looking forward to having Halloween over Nana's house today and showing off her pretty princess dress. So I put both their costumes in seperate bags, gave the bags to the kids and put them in hubby's car.

And then I said to my husband, AND I QUOTE: "PEYTON HAS HIS COSTUME IN HIS BAG. MAKE SURE HE TAKES IT INTO YOUR MOTHERS".

Fast forward an hour later. I'm talking to him after he gets to work. We're talking about his ride to work, the kids getting to his parents, etc. And inevitably, the question comes up:

ME: "Was Sophie excited to show your mom her costume?"
HIM: "Did she even have her costume with her?"
ME: "What do you MEAN? I gave you both their costumes this morning. Sophie's costume was strapped into the seat belt with her. Peyton's was in his hands and I told you he had it".
HIM: "OH. Was I looking at you when you told me about Peyton's costume?"
ME" "Yes".
HIM" "OH. I don't remember that conversation".

O.M.F.G.

So my 3 1/2 year old, who has been looking forward to Halloween for literally a MONTH, has no costume to show off to her grandmother and her Aunt today. Her little Halloween party they were going to have will still happen, but will happen sans costumes.

I know it's a little issue, but damnit, it freaking bothers me that he NEVER listens to me!! this was important to me!! This was important to the kids!! I wanted my in laws to see them in their costume, since they live 1/2 hr away.

Oh well.. There's always pictures.
