How did Peter Avoid getting caught in the yellow gentleman’s house

Peter pretended to have someone else in the boat with him..... two lovers on a tryst.

"Darling!" I said in my huskiest, deepest voice.

"Dearest!" I answered, with a little feminine giggle.

And then, in a tone of alarm: "Oh, Robbie, someone's
looking !"

"Be off with you!" the yellow gentleman shouted. "You can't tie up there ; do your billing and cooing some- where else, not under our windows !"
