The Green Thing

Checking out at the store, the young cashier suggested to the older woman that she should bring her own grocery bags because plastic bags weren't good for the environment.
The woman apologized and explained, "We didn't have this green thing back in my earlier days."
The clerk responded, "That's our problem today. Your generation did not care enough to save our environment for future generations."
