Today Megan and I were walking in a parking lot that had some construction going on and it was a little loud. Megan's poor ears are very sensitive to any loud noise other than her own. As we were walking toward the store at the other end Megan quickly dropped my hand, covered her ears, and yelled, "Cover your earwax!"
I laughed so hard. I don't think that she realized she said something funny at first, but when I couldn't stop laughing, she caught on and said it again.
