Heisenberg’s non-committal ness:
Lover: When do you think we’ll get married?
Heisenberg: When I love you enough, liebchen!
Lover: And when do you think that might be?
Heisenberg: Hmm, I can’t say. I either know how I feel about you or how my feelings towards you are changing, but not both.
Lover: It is obvious we don’t commute, I’ll just find somebody I commute with.
