Poor Boss

My boss just called. It's 9:00 a.m. I could not figure out why he would be calling : I thought maybe he was going to wish me a good trip to Kentucky.
He was wondering where I was. He had forgotten that I was leaving today. I had put a note up on his wall by his desk and cleared it with him. We had talked about it. Last week, on Friday, I said to him "Next week at this time I will be leaving for Louisville".
I think I covered all my bases and yet I still feel guilty. The poor guy has no dishwasher and he's going to be having a hard day today if he doesn't find someone.
I feel for him but I think reminding him a week ago was good enough on my part. I shouldn't have to remind him daily leading up to my departure. The guy is so flying by the seat of his pants it is incredible. And to think I thought he was calling to wish me a bon voyage.
