Last month I was letting myself into my flat just as one of our upstairs neighbours was coming down the stairs. Next thing you know she’s missed her footing, gone over on her ankle and is absolutely screaming in pain saying she’s heard a bone snap. I went and got some cushions, put her in the recovery poisition, called an ambulance, got her flatmate from upstairs and waited with them for the ambulance to arrive (three hours!). Had a good chat, got a load of gossip from the rest of the block tbh. Anyway, the ambulance finally arrived so I got out the way.
Haven’t seen her since, but I bumped into her flatmate last week, and she said that the thing that made her miss her footing was the fact that I was wearing bright red trainers and they dazzled her and distracted her as she was coming down the stairs. So it sounds like it was definitely my fault.
