Omitting critical pieces of information is not lying.

I am dog-sitting in a lovely house. (I don't own the house.) The other day a man came up and said, 'what a lovely paint job on your house! I especially like the sun design near the door! The place is just beautiful.'' And instead of saying, 'hey, this is not my house,' I just said, "Thanks,'' as if to imply I painted the house and own it.
