"If you live between two hostile neighbours who are constantly at each others throats, you are not likely to have a quiet life."
Border Reivers
Being the political football that they , and their homelands were , its' not surprising that their only loyalty was to their own blood .
What difference would we see had they united and become the third power in the region ?
I get the impression that the Border Reivers and the Highlanders had more more in common with each other , than with their immediate neighbours .
