madbird asked me to accompany her home, which seemed sensible. So I walked her home, we got to her doorsttep, she fumbled with keys and asked me to open the door for her. When I turned around to do so, she fell -she just went over, falling flat on her face, after whcih she lost consciousness, had quite a bit of blood on her head and face and was twitching and making little grunting noises. So I dialled 999 and was beginning to explain to the Ambulance people what was happening when the lady of the flat above hers arrived and started screaming. Ok, I won't relay the next twenty minutes but they weren't the most stress-free in my life. Eventually she was taken away in an ambulance, accompanied by her other flatmate (I think she's cloudgirl) ... she seems to be ok, I'm told by her flatmate, maxinemogadon, if bruised and shocked. Will try to speak to her later if I can.
