As an (ex-?) member of the Emms fan club, I will try add in my thoughts fairly.
I used to see Emms regularly (about once a year; my definition of regularly!). I always had a great time and she was one of my top three go-to escorts. However, I haven't seen her for a few years now and there are a couple of reasons for this. Firstly, she books up quickly and has few slots left on her profile, which makes things tricky for me. Secondly, I did find that her enthusiasm and engagement were declining and tending towards functional. The last time I saw Emms, I would rate her in the weak positive range (lovely person, good service, but lacking the previous energy and pizzazz). I am not surprised to see her ratings drifting down into the neutral range. I am happy to remember Emms as she was in the good old days.
