My Mom was very good about making me and my sister try something before rejecting it. (She made tuna noodle casserole once. It got a big veto and she never made it again. We had to try liver. We hated it. She hates it too, so she wasn't about to make us eat it. :-)

My grandfather treated each new food as an adventure, and so we got used to a variety of foods.

I remember my mother's friend and her kids came over for dinner (I must have been around 8 or so). My mother's friend made her kids PB&J because they didn't like what my mother made. I thought is was really rude, even then.
