Later, Steve asked "What's the difference between enchiladas, tacos, burritos, and fajitas?"
I was on a roll by now. I said "Well, an enchilada is a tortilla with stuff in it, whereas a taco is a tortilla with stuff in it..." Alan interrupted "Aren't taco shells hard?" I said "they can be soft tortillas. A Burrito, on the other hand are tortillas with stuff in it." I was starting to giggle uncontrollably. "You must be really tired" quipped Steve. I managed to get out "Fajitas are different. A fajita is a torilla with stuff in it", and almost fell off my chair.
