Before I start-I know what the right thing to do is and I did it. But ooooh the temptation!
My dd graduated 5 years ago. She and her stuff came briefly home, then moved off again, leaving behind a big box of books. Yesterday, with her permission, I opened the box to put the books on a recently cleared bookshelf. Among the books were a lot of papers and other bits and pieces which I put in a pile on the desk in what is still her room. One of these things is a sealed envelope addressed to Mum and Dad and decorated with happy little drawings. Obviously, I put it in the pile amongst other stuff so it looks as if I haven't seen it and obviously I'm not going to open it. But ooooh the curiosity!
