Mom used to be a gymnast, but there were no Ziploc bags near the balance beam

"I am about to be there, but I don't want to park and get out. My foot hurts."
"Why?"
"I didn't tell you? Did you see the skid mark in the kitchen?"
"Uh, no."
"I fell down."
"In the kitchen?"
"Yeah."
"When? What on earth were you doing?"
"I am surprised you didn't hear me. Yesterday morning. I was putting something in a Ziploc bag and fell down."
