We went out to dinner near Exmouth Market this evening, when we went back to the car around 9.10pm we walked past a locked playground, inside, alone was a child aged about 7 on a swing all dressed in white, giggling and saying "Higher! Higher!" AiBU completely unreasonable to find this freaky. It was so odd, I didn't know if stop to ask her if she was OK. DD also thought it strange, DH and DS didn't notice her.
