Because I have just seen this specific thing for the second time, I would like to say:
If I reblog your art, I do not expect you to reblog (or share!) my fic in return
If I comment on your fic, I do not expect you to comment on (or read!) mine in return
My enjoyment of anyone's work does not come with strings or expectations
My friendship is not a bill that you will have to pay later
That's it!
