She told me she had hair on her armpits. I looked, and sure enough like 5 long black hairs under each arm. I've been very reluctant to let her shave. It just seems like that means she's growing up. But, I had to give in. She wanted me to do the first one for her, and then she did the other. Now she's doomed to shaving all the time. I tried to tell her once you start you have to keep doing it. She didn't care. She wanted to do it and she did!
