Do some people on Mumsnet not realise how big the internet is?
There's a post on here today about a rowdy family on a UK beach and someone's reply is "It's not Polzeath, is it?"
What are the chances, eh?
It's like when someone posts about a grumpy shop assistant and someone answers "Do they work in Tesco Express in Hull?"
Or someone mentions their terrible boss and the reply comes in "Are their initials P.H?"
AIBU in thinking the people who post these things have the most restricted and delusional worldview?
