No, I have several older male friends who at a dinner party many, many years ago were shocked to discover that their possessions had been disposed of without them having been asked. I was shocked at the time, we were at least informed and asked to collect what we wanted when we left home in my family, but it was done in a rush and we had to make snap and sometimes unwise decisions. My youngest is 18 and he says that even now there are families who don't want their children to return home from university and are already disposing of theor possessions, it has really upset him (and them) as of course they have nowhere to store them. You would think they would be given the chance to at least store them in the loft or garage. I moved my daughter's possessions around from house to house for five years and then every time she came to visit I gave her a box to take back to sort out. I kept the best until last, so that now she has some lovely things for my GCs to keep and play with.
My son has only just started uni so I am carefully going through his possessions and sorting and tidying them. I am making up boxes for charity shops of things I know he doesn't want, some things that the GCs would like to play with now, but all the things like Brio and Lego and trains and stuff are being kept, along with his good books. Elderly joke books and stocking fillers will be disposed of. I think he is quite relieved that I am doing it, because he didn't know where to start and he knows that he would regret it if he threw stuff away in a hurry.
