You may be willing to share more of yourself than normal with your friends today. Still, keep in mind your motives for opening up. It's true that telling people about your background can give them a better context for understanding your quirks. However, people could feel resentful if you're trying to get out of trouble in the present by manipulating them with sad stories from your childhood -- even if they give you what you want in the moment out of guilt. Choose your words wisely.
