DP and I live on the top floor of a big Victorian house (converted into flats) overlooking a park in London. There is a big-ish front and back garden that can be accessed via a side gate that doesn’t lock. I came out the shower to see DP looking out the window into the night saying ‘what’s all that racket, there must be people in the garden’. I turned the lights off so we could both see better at which point a man comes pirouetting out from by the bins / side alley to the garden. He’s chattering and gabbling away to himself really loudly and sort of waltzing and pirouetting around out through the garden, into the road and then away. He looked like a normal balding man in clean clothes. But found him making the noises of two people and his languid movements very freaky. I lock my bike in the shed of the back garden every night when it’s dark and so does DP - and this has spooked me a bit! DP wondered if we should phone the police, but I said there was no point as he’s likely just a bit funny and was maybe just having a wee by the bins. WIBU?
