When your child loses their glasses and you have spent months looking for them and then finally just buy her knew ones. Which she forgets to wear because she got used to not wearing glasses. Then one day she says, "Hey mom, found my old glasses!"
Come to find out she put them in her telescope case when she was looking through her telescope.
Also she helps me list books on my online bookstore, trying to start a used bookstore. She corrects my mistakes in the condition comments. My fingers type faster than my brain works. She stops and actually reads it and fixes it. Thank goodness for a super smart kid, who will probably be my business partner when she's old enough...LOL
