Dear Pioneer,

Many thanks for your question. The expression 'You scratch my back and I'll scratch yours' is an old saying that was used to refer to an informal agreement. It usually meant 'I'll do this for you and you'll that for me'.
It's some kind of a 'mutualistic' relationship where two parties benefit from living closely with each other.

Dear Torsten. In Russian it sounds as: "Hand washes hand" Do you agree with it?
Pioneer

[Torsten]

You are exactly right. The German equivalent is the same as the Russian one: 'one hand washes the other'.

I didn't find the translation of the word "mutualistic" .What is it?
Pioneer

[Torsten]

Dear Pioneer,

A mutualistic relationship is a mutually beneficial association between different kinds of organisms.
'Mutual' means 'directed and received by each toward the other', 'reciprocal'.
You might have heard of 'mutual funds' or 'mutual insurance'.
