Blowing your nose in public is disgusting to me personally. I dont care if you use a napkin or hankerchief whatever. I am amazed to see people blowing their nose in public without any embarassment.

That's a curious world view. People should be embarrassed by things you personally find disgusting, even if they're within accepted social norms? And you are amazed that people do things are socially acceptable? Pardon me if I say that I find that a bit self-centered.

I'm not sure where you live, but at least in the US, it's acceptable to discreetly blow your nose in many public situations (the dining table not being one of those).

For full disclosure, I should mention that my nose runs a bit more than most. ;)

"I find that a bit self-centered."

I get that a lot so you are probably right :). I agree that in the US, it is an accepted social norm (I live in the US too) but I was just stating my personal opinion on the matter.

As for your own nose,blow away :). I promise to behave if I am around you

What is there to be embarrassed about?

I live in the US. I find it moderately disgusting. However, sneezing is acceptable when done down and away from the table.
