I feel the same way about things. Growing up poor I didn't really get much, so when I did I never used it for fear of losing it. My parents bought me a book of paper airplanes where you rip out the paper and follow the instructions to make a unique plane. I never used it. I still have the same problem with receiving food as a gift, I won't eat it. I make enough now to be comfortable, but I have shoes that are worn through that I won't throw away because I rarely got new shoes when I was a kid. I form crazy emotional attachments to gifts because they were so rare and typically meant someone I loved had to go without just to afford it.
