I am so with you. "Ask" drives me up a wall!
"I have something to ask of you" is not a novel term for request. And ask is softer than request, giving the other party more opening to decline. I don't hate it.
> I find that limiting the number of things that drive you up a wall is good.
Me too, but if this is really just a way of saying "this shouldn't upset you", you should just say that. As stated, it comes across as condescending.
