My s.o. and I argue about the stupidest things. For instance I say "touch wood" so as not to jinx something and he says it's "knock on wood", not "touch wood." A bunch of my LJ friends also say "knock on wood". Is that an American thing (and "touch wood" a Canadian or British thing?) Which expression do you use?
Do you say "knock on wood" or "touch wood"?
Something else (what?)
