Why I knew how to call you

I have been known to get after my kids for calling me all the time while I am trying to shop and run errands because it takes me so much longer to get things done. The other day while I was out running errands, Alexa called twice for little things and Hayden called to see if he could go to a friends house. Katie called next and she said "you know why I knew to call you? because of my coat." I thought she meant that she had left her coat at school and was telling me that she would get it the next day. She was actually saying that she knew how to call me (she knew my number) because I had written it in her coat. She said "I let Hayden use it to call you to see if he could play and now I'm calling, but I won't call all the time--I won't use it a lot". She is the funniest child. We are so glad that she came to us.
