Do you go too? Or do you just wave them off down the drive (and then crumple)?
DS has his own small car and won't be taking more stuff than will fit in it, so I'm kind of assuming that I should just leave him to it and wave him off. I've got to admit that I was surprised when I drove myself off to college 35 years ago and found a queue of parents with their children waiting to enrol. I had a very rural upbringing and it didn't occur to me that not everyone would take their own car, though to be fair it was very agricultural and most did.
Should I go to help him unpack and get settled in/buy stuff he didn't know that he needed, or pop down in a few weeks if he doesn't come home first. It's almost 4 hours away if that makes any difference.
