I guess what I'm saying is:
Essentially Status-Quo for many years (not all dandy, but more or less steady state). Scots decide they don't like it and want out maybe depending on if it suits them. So it kind of makes sense the rest aren't happy about it and would feel some animosity.
On the other hand. EU, major changes taking place. Would consider it as a valid basis for countries in it to be concerned and consider where they stand.
Should be stick it out through good times and bad. Not bail out when it's not looking too good.
I should point out that I'm not exactly a patriotic type. Plan to move somewhere sunny if finances and family arrangements allow in the future. Just kind of getting my head round why it would be annoying.
