I totally understood the unique conflict -- that's so funny! that's so wrong! -- these parents faced because something similar happened at our dinner table a couple weeks ago -- an incident that forced John and I to wear our "Responsible Parents" hats while inside we were belly laughing on the floor, doubled over in pre-teen hysterics.
And while I understand that some things will just fall flat on fickle young palettes, our typical house rule is "Try everything, just one bite; you never know what you might like." (It's not all annoying and sing-songy like that, though. That's just the spirit of the rule, Iago.)
