I was shown a video of someone else's hilarious Christmas memory. With true teenage arrogance, their daughter (who was going through an environmental phase of "unwanted presents and wrapping paper are wasteful") had declared that she did not want any wrapped presents at all: no socks, no jewellery, no books, nothing: just money, so she could choose how to spend it, and went as far as to declare that she would not even open any presents addressed to her.
Her parents granted her wish, but made her engage her brain for it, as one thing she did like was riddles and puzzles. When everyone else had opened their presents, the girl was blindfolded, and told that her cash was hidden in the room. She was made to hold a sign revealing the answer to everyone else, and then told to ask questions (only answerable by yes or no) to find out where it was; she was encouraged to move about between her questions. At first, she received loads of "no" answers, until she worked out that when she asked "is it in front of me", the answer was always yes, no matter which way she faced. After a long while, she found her cash: hidden inside her blindfold! At first, she found this utterly humiliating, but it was she who gleefully showed me the video, so she saw the funny side. She did admit later that she felt a bit left out when everyone else unwrapped presents, and she did not.
