Most Oddly Satisfying Video short story response

I'll be completely honest, I really have no idea what this article was about. i understand it is all about how a gelatin sphere gave one woman in particular relief from a hard day of being fired, and that she uses this gelatin sphere for all other attempts to relieve herself. However, the thumbnail portions completely confused me. I didn't understand the importance of the thumbnail. I took more interest when the author talked about people she sees everyday that are very similar to her to the point of her thinking that these people ARE here. I had to giggle when she called her therapist and asked to speak her but the receptionist said that she was with someone so the author just sighed and said, "ah, well played, other me." that does sound like something i would say. I see many people everyday where I see glimpses of myself in them. I think what it would be like if I was that person and that person was me, switched places. Then I get a weird feeling inside and come back to reality. I also liked the whole "that was another me," concept. I think we all are reminded of things that we did in the past and may be ashamed, embarrassed, or even reminiscent about those times and just say "yeah, but that was a different/another me." I am 100% guilty of thinking this! So while I was confused by some of this article, I definitely found myself relating to this author in author ways.
