Hamish, I am wondering if you have had any comments or looks whilst on your travels, such as too North America. I do think that the area one lives in might play a big part in this whole issue.
As for the age thing, well it might have a little part to play in it all, not in a bad way of course.
One might see you, (being such a fine Kilted Gentalman), whislt out and about and think to oneselfs, that this fine Kilted Man need not be bothered by any silly question or looks.
