I remember when I had to tape myself while I was student teaching. The video was painful to watch. My overall physical appearance had changed so much since the last time I had seen a video of myself--especially in the weight category. Meanwhile, what I thought was a relaxed posture looked lazy to the point of slovenly. I shudder to think of it.
Since then, due to Skype and other video-calling, I have a bit better understanding of the appearance I present--I just don't recognize the stranger on the video.
