Jeez, some people are very touchy aren't they.
Do I get grief for being English? of course I do.
Do I give it back to the Scots? again, of course I do.
Is any of it meant seriously? of course not.
while there has always been rivalry and banter between the 'home nations' very few people actually take it seriously, although most of those that do tend to be the non-English
(and yes that's an example of the p*ss-taking I'm on about)
