Ones I really like:
Favourite small pleasures - I love these threads.
Childhood memories, and nostalgia threads.
Rituals between OP and DH.
The "outraged" ones I enjoy reading are:
Man near a primary school - log it with 101? Even though he might be a parent, or someone using the bus stop?
Noisy students: perhaps because I've had this problem sometimes, and unlike other noisy neighbours, they are accountable to somebody.
Not wanting children to visit a church, hear a Bible story, hold a minute's silence, or receive a Noah's Ark toy. Have bingo card ready for "indoctrinate", "sky fairy", "imaginary friend", "otherwise intelligent people".
MAMILs. 'Nuff said. Although recently there was one where many of the replies defended the MAMIL, because the OP wanted to tease and mock him.
I said I'd cancel my DC's birthday party - do I have to follow through? Replies are usually: if you don't, they won't respect you, but if you do, they will hate you for ever, and remember it for ever.
Dealing with tantrums: most of the replies are quite sensible, I enjoy reading those.
The ones I don't like (and don't bother to read, because they're too predictable) are:
Victorian safe or similar, which turns out to be empty.
Virtue signalling about not flying, not driving, not using plastic.
People who "don't drive".
Baptising children to get them into a school, when you don't believe.
Shoes on or off.
DH's "outing" hobby.
Cat poo.
Loo brushes.
Anything with "AIBU to be livid/fuming/fewmin?"
