"I'd do it now, only I've got to buy some gold for a friend of mine.

Just let me know when it's perfectly convenient to take a lickin'." Tim shuffled off, glad to get away unharmed, and Dick turned to Phil.
"I'll give him a lickin' the first time I catch him, when there isn't a cop around," he said.
Phil left his friend at this point, for he saw by the clock on Trinity spire that it was time to go back to join Paul Hoffman, as he had agreed.

I may here add that Phil's wrongs were avenged that same evening, his friend, Dick, administered to Tim the promised "lickin'" with such good effect that the latter carried a black eye for a week afterwards..
