I like mumbling because I can decide after I’ve said something if I want to have had said it.
Me: [mumbles] That’s probably because you waste so much time watching TV.
Her: What did you say?
Me: Contemplates wisdom of having said that
Me: Huh? Nothing. Don’t worry about it.
Her: Nikhil, what the hell did you just say to me?
Me: Never mind!
Her: Sounds like you had something to say!
Me: Well, I retract it!
