It just seems unnecessary when they are just upsetting theirselves and spoiling it for other people.
I’m talking
“What’s your favourite treat food from the shops”
“Nothing. I live in a wooden crab infested shack and only eat mouldy dog food and sprouts”
Or
“What funny/silly nonsense did your family do with you as a child”
“Well they string me up and beat me with birches, I don’t know if that counts”
I understand hard lives, and it’s not been a picnic personally but I (and I assume others) read cheerful threads as nice escapism and happy memories and these posters are upsetting their selves and others
