I dated an
Archie once: he was an
Archibald, and genuinely Scottish. Also adult, and given to tossing the caber when back at home. Apart from that, he was rther dull really, and that's coloured my judgement. But I've got no problem with
Archie on an adult: and I couldn't take anyone of any age seriously if he answered to
Archibald. If not for the long-ago bf, I'd consider
Archibald, nn
Archie, for a Scottish terrier.
