I already have a salt shaker at my desk for my food. I can't hold any more salt.
As for astrals, it's not really an insult to you, as it is an extra challenge some people take up whenever they can. Some people just want to go for a stylish win if the opening is there, even if it means they might lose otherwise; it's worth it to them. You could think, "Well, it's an insult because they managed to astral me when they wouldn't be if I was better" but that's just getting mad that you got beaten. It doesn't have to be an insult.
