My wife used to complain about the stuff I was carrying...right up until she needed something.
Wife: "I'm cold, let me get that jacket out of your pack."
chaosmagnet: "No."
W: "Why not?!?"
c: "Get your own jacket."
W: "It's back at camp!"
c: "I guess you should have brought one."
I ended up letting her have the jacket, but after a few similar events she stopped making fun of me.
