I thought about it. At first, I was a little worried. Were there any repercussions if someone considers you insane? Since, my behavior was well within what I considered "normal", I wondered what inspired the perception. Was it something I said? What did I do? Is she the only person that feels this way?
So, after ten minutes of introspection, I came to the conclusion my friend was pulling my leg, or that it was a little nice to be considered crazy. It keeps people on edge and they generally won't make the mistake of double-crossing a crazy person.
