Things You May Not Know About Me:

At my swearing-in ceremony, a senior partner introduced me as “Possibly the only member of the Greensboro Bar who was previously a shepherd on the Isle of Skye.” It’s true, and while I still have a sheepdog, neither he nor I would know what to do if we saw a sheep in Greensboro. 

I met my wife in Glasgow, Scotland, while she was on a study abroad program from the University of North Carolina at Chapel Hill. She returned home to North Carolina engaged. Warning to all parents: Don’t send your children on study abroad programs! 

I enjoy playing and watching football (called 'soccer' on this side of The Pond). I follow a team in Paisley, Scotland called St. Mirren. They’re not very good. 

The MacSween clan motto is “Constant and faithful.” My mother’s clan is MacGillivray. The MacGillivray clan motto is “Touch not this cat.“ No, I don’t understand what it means either. 

My cousin (John Lowrie Morrison aka “Jolomo”) is a famous Scottish artist. I have absolutely no artistic skills. 

If I were not a lawyer, then perhaps I’d still be a shepherd on the Isle of Skye.
