Dear Man at Discount Grocery Store:
I've been meaning to tell you, how horrible and awkward you made the air at the checkout stand at unnamed grocery store. When you yell at and demean your kids in public and in front of strangers, you really make yourself look bad. I just wonder what it's like behind closed doors if you feel that comfortable talking to them like that in front of other people. And when your son asked you to buy him gum and said "But dad, you owe me", you responded with "I don't owe you nothin". Well, you're wrong. You owe your children many things. You owe it to them to love them and treat them kindly. You owe them support and security and a happy home. You owe them a nice father and mother who teach them how to be kind, generous, smart and successful in life. How's it going with that?
And p.s. When you forced that checker to exchange your Sunkist soda for Shasta, you totally lost 'cause the Sunkist cost more. So you're out some change. Just wanted to rub that in your face. Now stop yelling at your kids so much.
