I found out that my mum threw away my Charlie and the Chocolate Factory book yesterday, and got really upset about it. (both at losing the book and her throwing it away) To try to calm myself down, I actually typed this out. It's not the full story and it might not make much sense, but here it is:
You don’t just throw away other people’s things like that. You will never be able to guess just how much a tattered book or small gimcrack could mean to someone else. Even if you bought it for someone else, or if it’s something the two of you share – something seemingly worthless to you could be of infinite value to someone else.
