I want you to be concerned about your next door neighbor. Do you know your next door neighbor?
You should never have to say hello or goodbye. Even at work sometimes, and I know this is very unpopular, is that if I'm going to work every single day, I don't think you should have to hug people hello every single day when you come to work. I saw you Monday!
When I was a kid, I was surrounded by girls: older sisters, older girl cousins just down the street... except for an older boy named Vito who threw rocks. Each year I would wish for a baby brother. It never happened.
