Last week I was driving the local school bus and 12 kids got on. At the next stop, 5 got off and 7 got on. At the next stop, 10 got on and 1 got off. At the last stop 23 kids got off. What was the name of the bus driver?

Since I was driving the bus and my name is Kev the answer must be Kev. If you try this puzzle on someone else, use your own name.
