When somene pays for me, I dont quibble about splitting it even. I use it as a bench mark, but I assume somsone else wont pay.
Also I know theres times I've screwed up and didn't give the fair amount (moatly due to not thinking or being aware of costs), so I try to bump it up and do a bit extra from now on.
I have conversations with my spouse sometimes where I am asking for information, and she reads me the article.
I can read it myself! What did you find interesting?
