I actually have a Clemintine tree. It’s inside for the winter but it just flowered and it looks like it will be producing a considerable amount of fruit this summer.
As to the picky eaters I don’t seem to remember many picky eaters as a kid. Nobody I know got mac and cheese or hot dogs when they didn’t like dinner. You ate or your didn’t that was it. But then that was before schools sold junk food all day long.
The one thing I can say is that picky eaters are rare in large families. I’m the oldest of five kids. Only eight years seperates me from my youngest sister. We were a working class family so food wasn’t scarse but the budget was limited. You ate what you were given and you ate fast if you wanted seconds. This became an issue when my brothers and I were all teens at the same time. For most of the 80’s leftovers were non existant in our house. My parents treated us much the same as WhyNot does. Eat it or go to bed hungry.
