"Then why are you chatting together like you're bestest friends?"
My 6-year-old daughter asked me this question at least three times while we ran errands.
My mother used to do this too: strike up conversations with complete strangers in the store, in line at the post office and in doctors’ waiting rooms. To my young mind, I couldn't comprehend how two strangers could be giggling together like old college roomies after only two lines of dialogue. Now I know. They're all fellow mommies: members of Club Mom.
