Eh. The biggest thing I've noticed with the Scottish, especially since moving out of the country, is that when we've had a drink or two (and sometimes when we haven't) we've got a really bad habit of talking over each other. Which is sort of fine, when everyone else does it, but when you talk to people from elsewhere they just find it incredibly rude!
Thankfully I've managed a fair deal of restraint on that one these days. I've learned that not every beer needs to be preluded by whiskey.
