I&#x27;m Scottish by birth, but was raised in the US. I don&#x27;t have a problem with any of the Scottish accents, but American friends consistently have trouble understanding Glasgow patter and certain highland accents.  Heck, I add a roommate in college who needed captions for Trainspotting!<p>That said, it tends to be as much a vocabulary problem as the accent itself.  Lot&#x27;s of colloquialisms to learn.
