You were lucky that the women didn’t take it negatively, and that your boss wasn’t around. The woman could have scream predator right there and then and she could have ruined you if she was bad enough.
I used to be in the same situation, and I was almost ruined by my “boss”. Some years ago I was a teaching assistant for this woman who appeared very, very friendly and loveable. When I first came to my current workplace, she was the first person to approach me and talk to me. She even gave me a gift to “aid with my job”. She was also the most popular person among the employees for her skill and charm. One day I was super sick and I was unable to focus on my surrounding. I remember at one point she asked me to help her around with the kids. I didn’t remember the exact detail, but I went out to do something and the came back and completely forgotten about what she said. I was feeling dizzy so I sat down to calm myself down. Just then I heard her screaming at me to stand up and do my job. I heard a stream of word vomit about how angry she was and how she had to work hard and how I was goofing around. After the class was done, she asked me to go meet her privately. And what she did was going on another rant about how much she loved me and how much I should appreciate that. She said that she asked me to come talk to her because she regarded me as her sister and she only wanted good things for me. Errr… if she had really loved me that much, she would have just repeated what she said earlier and waited for my explanation, not jumping at me like a freaking lion like that!
And at that moment, I realized that all of her friendly demeanor I saw earlier was just a facade she carefully crafted to prey on people’s trust. I started to observe her behavior around the children and that was also exactly what she did to them.
That wasn’t the first time I had a run-in with her. After the incident, she suddenly went back to her friendly self as if nothing had happened, but I no longer bought it. She would organize the kids to sing Happy Birthday for me one day, and then the next day shamed me for a mistake I made long in the past. She was so popular that no one had anything bad to say about her, so I was completely alone in dealing with her. My interaction with her dealt a lot of damage to my self-esteem until she moved out of the country to study abroad. I couldn’t be any happier.
Sorry that I got so emotional, but that was one of the worse time in my life.
