I've thought all of these. Full house, caller! Come and check my MN bingo card!
Two more: when someone posts saying something like AIBU- MiL set fire to my new, made to measure £££ curtains because she thinks they didn't go with the carpet. She's done similar before; firebombing my kitchen and yet again won't pay up- should we finally go NC before she turns on my new, clashing sofa? You get a load of people trying to "help" by focusing on the interiors and suggesting that they'd never pay what you paid for curtains and let MN find you replacements etc rather than focusing on the fact you're dealing with a family nightmare and a pyromaniac.
Might just be me with bitch in my user name, but people who disagree with your post won't just say you're"vile" or "nasty" or similar if "vile bitch" or "nasty cow" or "entitled little cow" etc. AIBU is the vipers nest yes, but that seems unnecessary and pointlessly spiteful. I pointed out to someone with a different view to me saying I was clearly a "bitch by name, bitch by nature" that she'd stooped to name slinging- not me. Therefore, it was pretty obvious who the real bitch was on that thread, sweetie. Lots of nasty little digs, too. And it's never on serious, political threads or huge, dramatic situations etc either. It'll be on a random opinion thread.
