Probably a mentally ill woman who realized she is no longer a young girl with her whole life ahead of her and got triggered hard.
What word should we use now that we can't say m*ddle-aged without triggering people? Postwall? Old? Age-challenged? /jk Lol. In before you can't call 10 year olds kids since it makes 55 year old women feel old.
Sounds like the type you can trigger by calling "ma'am". Then when they get angry, twist the knife by saying you were raised to speak respectfully to your elders.
