Many years ago I was working for a company that sent me on business trips. When I left, my cat would stay with friends, whom he loved. Every time I came back from a trip, he would snub me. For two to three days, he would spend every moment sitting in the same room as me with his back to me. He wouldn't look at me. If I tried to pet him, he would run off, only to come back and resume snubbing me a few minutes later. He would take food from me, of course. He wasn't crazy. Then, after those two or three days, he would then forgive me and resume normal snuggles, but for those couple of days, I was dead to him.
