Well you got your first fall out of the way. I think almost all have at least one, I have had a few myself.
I also agree that learning to unclip with either foot is good, but I have not mastered it myself. To be honest however, my husband feels that unclipping with the right foot is best so if you stumble & by chance fall you are falling of the opposite side of traffic.
