I may have stumbled upon a second career within the teaching profession. That of substituting for teachers within the building when there isn't one available. I can't say it is something that I particularly want to do, but it does present some opportunities. For one, it gives me the opportunity to walk a mile in someone else’s shoes, thus gaining a deeper appreciation for the unique challenges and rewards faced by others in this wonderful profession. Another benefit is that I may be able to earn a bit of additional money. I'm not sure how much this is, but I'm thinking it probably isn't much because I'm already there.
