One day my mother needed to borrow a t-shirt to wear to the gym. She went into my bedroom dresser and borrowed a purple t-shirt which had letters on the back. She didn't see the letters so when someone walked up to her in the gym and said, "Oh my God, you're in D Phi E! I'm in D Phi E!" My mother had no idea what this woman was talking about until she took off the shirt and saw the letters on the back. She told me the story, and I thought that it was funny, but she felt bad because she looked at that very young woman like she was nuts.
