Some people respectfully emulate, while others disrespectfully imitate, but in both cases, it is usually a conscious, deliberate choice.

Sincerety seems to me the paramount virtue.

Maggie T is my "most unfavorite" resident of the Celtic Isles :) and I also concur in SteveP's "take" and contribution on this thread. I'll have to ponder this twist of fate over a pint. I'll have one for you as well.
