Girls, ??‍♀️I had an appointment at the gynecological consultation yes…

Girls, ??‍♀️I had an appointment at the gynecological consultation yesterday, we did CTG, after finishing I was asked to take a picture of the result (this is not the first CTG). In general, I took a photo, but immediately asked "for what purpose do I need this photo?". They both answered me "for beauty"; "as a memory". How can I understand this, girls? ? What kind of jokes are these?? I left there and didn't ask further questions, maybe I don't understand something
