Splinter issues

She got a splinter in her foot about ten days ago. It didn't look like a big deal, so I told her it would work itself out. It hadn't done that by yesterday, so she asked me if I thought she should soak it in hot water and I said yes. About 30 minutes later she presents me with a waterlogged sliver of wood about a quarter-inch long and shows me the hole in her foot it came out of. I was impressed. 

My next pass through the living room, I see her with her foot in a pan of water. I ask what she's doing. "Well," she says, "I have this splinter in my foot and I thought if I soaked it in hot water, I could get it out." 

"You already got it out," I said.

"I did?"

"Yes, I think you got all of it."

"But it still hurts, and it's red."

"Well there's still a lot of anger in there. Give it some time."

She wasn't sure whether to trust me, but she dried her foot and put away the pan.

UPDATE 

This evening she came upstairs looking quite happy.

"I think that thing in my foot worked itself out," she said. "It doesn't hurt and I can walk normal..."

"It didn't work itself out, you squeezed it out, yesterday..."

"I did?"

"You did."

She made a muscle pose with her right bicep, grinned and looked pleased with herself, and she had a pleasant night.
