I just want to add to what Job said. I saw it first-hand with my H, he would start doing something around the house, then start something else, then get sidetracked by something else. He would leave to go "here", and end up going "there", completely forgetting about going "here"! He continues to forget things on a regular basis. He would have really dumb excuses and lies to cover, but I realized I think it came more from being either embarrassed or confused.
Their brains really are mush. Don't take it personal, I really do think a lot of it is unintentional.
