My wife told me to 'just take care of the kids for an hour.' I made sandwiches. They ate the sandwiches. I made fruit. They ate the fruit. I put on a cartoon. They watched the cartoon. After an hour, she came back and said, 'So, how was it?' I said, 'I fed them. I entertained them. I existed in the same room as them for sixty minutes. I was present. I was in the room. The room had them in it. And I was in the room. We were co-located for sixty minutes.'
