Barter

I'll give you brownie points and pinking shears if you can teach me how to whistle with my fingers and find the guy in the white car, I promise.

I'll bake bread and cakes and cookies for you every Monday if you teach me how to play chess, do advanced calculus and help me park a car.
I'll give you a deep tissue massage every day if you play guitar with me every day during the evening and not get bored of my lame efforts at the end of it.

I'll knit you a sweater if you promise to fold the laundered clothes and keep them in the cupboard.

I'll let you play any card of your choice if you can make me quit smoking without being judgmental.

I'll be nice if you are nice.

I'll be kind if you are kind.

I'll play if you play.
