A bowl

One evening about a month ago, Walter wasn't feeling great. While he sat on my lap I noticed his fever rising and I went to get a bowl. I brought it to him just in time to throw up. He then felt a bit better and went to bed and was fine after that. This morning he woke up and complained about his stomach so I asked if I should get a bowl and he agreed. When I brought it back he looked relieved and made some gagging noises into it for a minute. Looking up at me sadly he said, "It's not working."
