Here's the kind of thing I'm concerned about.

I was reading about remodeling the kitchen, and the author said that young people are afraid of stoves. All their lives they have heated things in the microwave and never turned on an oven. Obviously, one cannot become a good, lifelong cook using nothing but a microwave. Therefore, modern manufacturers are are producing ovens that look like microwaves.

So now I'm wondering what other unknown differences there might be between him and me. (Thanks, Rap, for the soup idea, which is based on true interactions between generations.)
