When I leave for meetings I always take my bag with my computer in it. That's to prevent anxiety in case a meteorite destroys the highway and separates me from my computer.
I came back from a meeting in San Jose, parked the car, came into the house, said hi to Rosie, and then realized I didn't have my bag. So I went back to the car, but it wasn't there. I went to the other car wondering whether somehow I had put it in the other car. No. I was really hoping I didn't leave the bag in San Jose. I went back to the cars... Nothing. I hadn't even taken the bag with me. I hadn't even put my computer in the bag. I forgot the bag and never even noticed (hence I also avoided the separation anxiety).
