Are they more receptive to feedback when you just launch straight into it? Or is there something different that you do to prime them to be receptive?

As in it doesn't get that far. I've literally seen men say "would you mind if I give you some feedback" and that was received as a condescending thing to ask someone.

This is of course anecdotal, so I'm not trying to paint anyone with a broad brush. Just wanted to point out that in my experience, asking if you can give feedback/advice/etc isn't always well-received. I can't imagine unsolicited feedback would've been any better received in those situations.

If people take this as condescending then maybe they aren't mature enough to be worth interacting with, though.
