And you still revisit years later.
Mine- I was a 26 year old mother of two. First ever playschool trip where the parents jolly along to the farm with the kids. There was a mum there that I was friends with. The only one, as it was quite a snooty and cliquey village, but our kids liked each other, so that meant we spoke to one another. I had a teething, colicky baby strapped to the front of me and a clingy pre schooler on my hip. Pre schooler finally went off with the staff to pet some chicks and ducklings and we parents were allowed to get a coffee and rest our ears from fifty billion questions and whinges. The baby finally fell asleep after having me up all night, and so I was really looking forward to a hot drink and a slice of cake. My mum friend had been clucking sympathetically at me while my baby was fussing and I'd appreciated the solidarity. I offered to get coffee for us both. She accepted and then was umming and ahhing over whether or not she wanted cake, so I bought two slices and brought them back, feeling like I was doing something really nice for someone who had been nice to me, especially since I only really had £10 to my name.
She looked at me like I'd spat in her drink and shrilled out, really loudly "I can't eat cake, you silly cow!! I'm on weight watchers!!" Really took the wind out of my sails. I was just stunned. She took her coffee that I had paid for and sat with some other mums who loudly discussed saboteurs and how I looked like I could do with less cake myself. My baby was 11 weeks old. I couldn't eat either slice of cake, I was so shaky and upset. She wouldn't sit with me on the way back and never really spoke to me again.
