I was in the grocery store today when a woman came up behind me...

"Excuse me..." she said.
"Yes"
"About a year ago you gave me some really great advice and I just wanted to thank you."
"Me?"
"Yea.... you told me that I should put my daughter down for a nap every two-and-a-half hours and now she sleeps through the night and takes regular naps."
"Was that here?"
"Uh-huh... you started talking to me here at Publix and I said my daughter wasn't sleeping and that's when you told me to put her down every two-and-a-half hours. You made my life better."
"Wow, how about that?"
"I have always remembered it and I've always hoped that I might run into you so I could thank you."
"That's so great!" Listen, could you call my wife and tell her not to be embarrassed when I talk to total strangers in the grocery store?"
