One day when we were coming home, there was a police car in the park near our house, so Mimi and Oliver went to investigate (the reason remained unclear, but at least Oliver got to explore).

The next day, Oliver and I had this exchange:

Oliver: Why was there a police car in the park?
Me: Umm, I think it was to check that everything was okay.
Oliver: And there was a computer in there. That's cool.
Me: Yes, that helps the police officers do their work.
Oliver: Yeah. If someone is in trouble, they have to make an e-mail.

Talking about a classmate:

'E's mommy is going to have a baby. I think he's not wearing any clothes now. Just a diaper.'

Oliver spots the 'om' symbol:

'That says three! And that means me! A three and an O!'
