I don't see much of difference. They lied to you when they snuck the smokes, right?
You can now only assume they weren't lying and or cheating about other things.
Sorry to burst your pompous bubble, but no they didn't lie. I never asked, but it came out years later. I did tell them I'd rather they never start smoking, however, since I smoke it would be rather two-faced to insist they never do. You really don't see the difference? Please say you don't have children.
