Greg: I'm sorry if I made you mad.

Harold: you're sorry 'if'?

Greg: Yeah.

Harold: As in if you made me mad, which you did, then you're sorry.

Greg: No sorry if I made you mad, because I don't think I did.

Harold: Well you did, so regardless of how 'sorry if' you are, you made me mad.

Greg: OK! Sorry!

Harold: Now, that's not a sorry tone.
