I'm trying to convey "If you do x, we'll call it even."
So my sentence is:
我们可以互相学习，我教你滑雪，作为回报你可以教我什么呢？ we can both learn from each other... I teach you to ski... and in return what can you teach me?
我没有什么特长 I don't have any specialties
So I was going to say:
How about you cook for me and we'll call it even.
How would I say that?
