After watching a Life Alert commercial on television.

"Momma, you need one of those."

"One of what, honey?" (I seldom pay attention to tv commercials)

"One of those buttons."

"Huh?"

"You know, you wear it around your neck and if you fall down you push the button and someone comes to help. You need one of those buttons. Let's go get one for you."

Suddenly, I realize what she's talking about: "Oooooh.... well... honey what makes you think I need one of those buttons?"

"Because when you fall down, you can call me and I can come help you."
