Probably a hint

After the boy and I had been browsing the flea market for a while this weekend, he informed me he was done and asked if we could go home now. Not quite finished myself, I assured him I'd be ready to leave soon. A few minutes later, he started to quietly sing to himself:

"Be patient (be patient) with everyone.
Be patient (be patient) with everyone.
Be patient with everyone,
First Thessalonians,
five, verse fourteen."

Hint taken, mister!

(By the way, can I just take this opportunity to once again recommend Songs for Saplings? Two years later and it's still one of our favourites!)
