Rudeness

So I went to Cracker Barrel today with Rod and family for a farewell luncheon before they head back to Florida. The friendly young, presumably new waitress (she had only one star on her apron) asked Rod, "Where are you from?" He replied Trinidad, to which she responded, "Where's that?" So he explained. Then others ordered and I ordered and she asked me, "Are you from Trinidad too?" Now I'm not sure what about me seemed foreign exactly, and maybe she was being sweet and new and friendly, and I really should start with the nice reply rather than the funny one, but whatever the reason I responded, "No, I'm from another world entirely." I was going to follow up with, "I'm from California" but Rod had busted up laughing and the waitress had already moved on in her job and I was left having just replied to her perfectly nice question, well, rudely. I mean, it was funny in the moment, but on later thought I realized, man that was uncalled for. Luckily the waitress appeared to take no offense and delivered our food as perkily as she took our order. Of course, a bit of spittle would be undetectable in my bowl of chicken and dumplings. Hmmm.
