It's so frustrating. The OP will ask, for example, 'can anyone recommend the best way of getting from Brighton to Norfolk? I'm travelling alone and can't drive', and there'll be numerous responses saying 'the public transport isn't great, I'd take your car OP'.
Or there'll be a post saying 'I'm upset because my friend seems to have ghosted me. I've tried ringing and texting and even knocked on her door! She's alive because she's posting on Facebook', and then there's the answers of 'are you not worried something has happened to her OP?! If it was my friend I'd go round and knock on the door!'
It happens in simple threads to upsetting ones and it drives me insane.
