Growing up and getting practical

What defines a young and carefree teen from an elderly and conscientious old biddy? I'll tell you what. Practicality! Young people don't do being practical. Biddies do. So, what if a seemingly young person wanted to purchase a shopping trolley? I'd say it was a pretty defining moment in this person's growing up. It'd highlight the difference between her youth and her ever inevitable spinsterhood.

I can't wait until I get one!
