Dave did not go to Las Vegas. He went to bed with a temperature above 101 and a rough throat. In the morning he didn't get up and go, thus saving the other passengers from infection and himself from a rough trip. Instead he stayed at our house all day and went back to his after dinner.
I had made plans to have breakfast with Helena and for the two of us to visit Arvin. So I stuck to those plans and Dave hung out on his own. He was happy reading and napping until we got back. Steve came over and I made dinner for everybody. We played another game and Dave headed home, dropping Helena off at her apartment on the way. Steve and I played another game and watched some TV before he headed off home and I headed to bed.
