I have a friend, one of those real ones that your kid brings over to you on the playground or in front of the school and says, “Here, this is so and so’s Mum, you’ll love her.”  There are other real ones, like the girl you met Freshman year in college who is so different from you and yet so alike that you can’t stop listening to her stories and you start using the same soap she does because you want to smell just like her.  But more about her, another time.
