Since we moved to Vancouver this last year we have become consumers of public transportation. My son wanted to pull the bell on the bus, so I told him I would tell him when we could ring the bell.
A block and a half from our stop I said "Ding it"
M looks at me. "Ding it!"
Another stare, and a glancing around. "Ding the bell!"
"Oh. I Didnt know you meant for me to pull the cord! I thought you were pretend swearing!"
"Ding it!" has now entered our family lexicon.
