My brother is a radio astronomer.
When I asked him what that means, he said: I send radio waves out into space, and based on what comes back, I form an image of what is out there.
Oh, I said, like what I do with e-mails.
He looked at me and raised an eyebrow.
I love it when he does that.
Alles uit de kast

Zalig! Ik zie het zo voor mij 🙂
