On the way to Nursery for the first time

Title says it all. Excited little girl set off. When we arrived put on her plimsolls, sat herself down at the playdough and dismissed Mummy. I was guessing that was a good thing. At pick up the teacher's report was that it was as if she had always been there, I'm still guessing that is a good thing and hoping that I am not supposed to read through the lines.
