Family conversation
Me: "I hate having to do this, it's painful, I have to force myself to do it."
Husband: "That's exactly how I feel about what I am starting now."
Me: "You can't feel as bad as me, I have been trying to finish this for four years!"
Husband: "OK, so you win this time, but afterwards, I want to suffer more."
Me: "Until I have submitted this thesis, I hurt more than you, always!"
Husband: "Then get it done!"

I guess I ought to take his advice.
