Well I came on here to say I learned that opening the door to callers is just asking to be killed, but leaving your doors unlocked whilst you are in the house is de rigeur and it's totally crazy to lock them. But looks like I may have been beaten to it.
That it's perfectly fine to not answer a text for weeks because everyone is SOOOOO busy, but that replying with a quick 'thumbs up' emoji as acknowledgement and assent is both rude and passive aggressive.
That the Cost of Living has everyone impoverished, even those on hundreds of thousands of pounds. But not so much that they would turn their heating below 23 degrees or stop washing their clothes twice after each wear, plus bedding every day, and towels if they so much as get a bit damp from hands being wiped on them. And that I am definitely a minger because things only get washed when they fail a sniff test. It's like deodorant and showers never happened.
That it's very important to hate children and all things they love - Halloween, Christmas, fireworks, bonfires, Easter eggs, social media etc etc.
That gentle parenting is permissive parenting. This one really pisses me off, as gentle parenting is NOT permissive, and I wish I had parented even more gently than I did. It was my natural parenting style, but I used the naughty step, because I was unaware of gentle parenting in the 00s. But oh no, any example of permissive parenting gets slagged as being 'gentle'.
That if you want to scam loads of people, MN is full of people who would 'rather give to a scammer than have a needy person go without'
But also that people have big hearts and will give really good advice and emotional support when someone is genuinely in need.
