About the social faux pas mentioned and not being invited to dinner...

Those dinners probably aint worth going to in the first place. You aint missing much.

Nix, here on our forum, was wearing my family tartan, Douglas. I've broke bread with him on a few occasions now. I'd gladly do it again. I've not yet been offended by him, or whatever tartan he wears.

The people are far more important than the tartan that they wear. Focus on them, and the rest will fall in to place.
