I was sitting quietly on the deck yesterday afternoon. All three of my kids were in the yard playing. Here's an exchange I overheard between my son and his little sister.
"Dee-Dah, you shoe untied."
"I know, Biddy, it's fine."
"Dee-Dah, I fix it."
(bends down to try and reach it as my son backs away)
"No Biddy, it's fine."
"You might twip."
"I won't trip, I'll just tie it, see?"
"You push me on the swing now?"
