Ian and I were eating lunch together and working on some Puzzle Buzz books (LOVE those!) and he suddenly had to go to the bathroom. He told me it would be a long one...so I said I'd go upstairs and get some chores done.
He says, "No, Mom. Don't go up there while I'm still down here. Or, wait. You know how long I usually take, so go upstairs, but right before it is time for me to be done, come downstairs again so you can be here with me."
