Trevor started our session today by asking if anybody in the room was twenty-two. To my surprise (I thought everybody is twenty-four) two people said they were; he asked one of them to be twenty-three and the other one to be twenty-one. Then he asked all of us to write our age down. Then, to reverse the digits. Then, to take away the smaller number from the bigger number. And then to add the digits of the number we got. As you can imagine, much confusion ensued.

In the end, he went around the circle asking everybody what they have got.

“Nine.”
“Nine.”
“Nine!”
“Nine too.”
“Nine…”
“Nine.”
“Nine.”
“Nine.”
“Three?”
“Two!”

Teeheeheeheehee.
