Well, if you are telling me about problem X, which could easily resolved and which would be useful and beneficial for you, and we could solve it with low transactions costs, and i present you the solution Y to your problem X: Why should this be offensive? (obviously they have some "logistics alignment problem", if the have those dicussions?)

example: im living alone and i also hired someone to do this. I do not get whats wrong about a useful suggestion? And esp. in this case, its not about the money that they do not hire someone

People often make the mistake of thinking “I want to rant about X” means “I’d like a near stranger to tell me how to fix X”.

“Why don’t you just get someone in to clean”, specifically, may also cause a perception of criticism. Perhaps they want their kids to learn to do the chore for when they live alone. Etc.

OK, i get the idea of that stranger guy in the metro telling you how to fix your life when he saw that you are scrolling whatever self-help-page.

Well, in this specific case: This wasnt our first date, we met already several times before; so i was not just throwing over this idea as a stranger.

And i get the educational-track here that you are pointing on - the thing is, if you would know about their frequency (as told by her), then you see that a critical level may be achieved at which you shouldn bet on "if-its-dirty-enough-the-kids-will-do-it-somewhen" ;-) ;-)
