I believe the long-term emptiness of my "about me" section also says I can be pretty reserved. I don't put much out there until I'm comfortable doing so. As an introvert, I generally keep to myself. I often feel like the living opposite of gregarious. I prefer to listen rather than talk until engaged in a topic I feel passionately about.
In keeping with the spirit of who I am, I will keep this short and to the point. Although I'm reserved, there are no stupid questions. If you'd like to know more about me, please feel free to ask. The worst you'll get is an, "I'd rather not answer that."
For me, "Available" doesn't imply single, please be aware.
