"What is a bruise?" and "How do we laugh?" and "What does it mean to jump?"
Owen piped up and asked, "What is a cookie?"
And I just laughed. Because his tone of voice was so . . . familiar. It was clear he was imitating his brother. Which means that I'm not crazy. That Sam is asking an absurd number of questions recently. Even Owen is noticing.
Also, I know what a cookie is.
Then Owen asked, "What is a jumrip?"
"A jumrip. What is a jumrip?"
Okay, now you're just making stuff up.
