On the Video:
- I didn't see Terri. She saw me. I walked past her. She yelled out to me, got my attention.
- she (Terri) is quiet and not social
My understanding is that this woman worked at TH's gym. So, normally if she saw her, the woman would be "on duty", and TH would be working out. Not a social situation.
Perhaps TH would be more chatty and social when the other woman was "off the clock" and TH wasn't mentally in whatever sort of "zone" she gets into to work out. (As a former bodybuilder, she might take working out very seriously.)
Also - the article mentions that the woman DID work at TH's gym, but has transferred to another location. I'm curious whether she was currently working at TH's gym as of that morning. If not, and TH hadn't seen her in awhile, that would be even more reason to stop and chat.
