Ella's Practical Solution
We were driving in the car yesterday when Ella exclaimed from the back of the car. Here is our conversation:
Ella: OH!
Me: What's wrong Ella?
Ella: Booger! [holds up the offending little thing on the tip of her finger]
Me: Oh--do you need me to give you a tissue?
Ella: [holding up a "clean" finger] No. Me eat it.
Lovely.
