My family is almost 100% Asker. When I got to college, I drove Guessers nuts. They thought I was so selfish and would blow up at me (from my perspective) out of nowhere.
"No" is always a perfectly fine and polite answer from my perspective
A uni pal with the samey attitude had a wonderful motto - "better to look stupid than to be stupid".
Except a lot af askers will put you in an uncomfortable spot. No I don't want you and your family staying at my house while you are in town.
It's a shame more people don't assume good faith so we can have more direct and honest communication with each other.
