Be weary of people who use you as a doormat. Your role in their life may not be so clear, to you or them, especially if they're good at maintenance. They may put in the energy to clean up mistakes, maybe even make you feel special by showing you off, or, even, apologize when you feel as if you've been walked all over. If you see yourself as playing the role of a fixture, a convenient accent in someone's life, and you give them credit for rising to the occasion for regular maintenance-- I'm sorry to point out: a doormat is a doormat. Even if they treat you with the utmost care to preserve your grandeur, YOU ARE NOT A DOORMAT TO BEGIN WITH. So, get off the floor, dust yourself off, and get the hell out of there!
