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!
My mom was a single mom and she had enough on her plate. I knew when I was doing something I wasn't supposed to and I tried to keep her from finding out about it. I did a pretty good job of that.
