"Hey, Dad," one of my kids asked the other day, "what was your favourite fast food when you were growing up?" "We didn't have fast food when I was growing up," I informed him."All the food was slow." "Where did you eat?" "It was a place called 'at home'." I explained."Grandma cooked every day and when Grandpa got home from work, we sat down together at the dining table, and if I didn't like what she put on my plate I was allowed to sit there until I liked it." Some parents never owned their own houses, set foot on a golf course, travelled out of the country or had a credit card. My parents have never driven me to soccer practice.This was mostly because we never had heard of soccer.I had a bicycle that weighed probably 50 pounds, and only had one speed.We didn't have a television in our house until I was 11.I was 13 when I tasted my first pizza; it was called "pizza pie".When I bit into it, I burned the roof of my mouth and the cheese slid off, swung down, plastered itself against my chin and burned that, too.It's still the best pizza I ever had. I delivered newspapers, six days a week .The paper cost 7 cents, of which I got to keep 2 cents.I had to get up at 4:00 a.m.every morning.On Saturday, I had to collect the 42 cents from my customers.My favourite customers were the ones who gave me 50 cents and told me to keep the change. If you grew up in a generation before there was fast food, you may want to share some of these memories with your children or grandchildren. Growing up isn't what it used to be, is it? The writer's purpose of writing this passage is to   _  .
