I've got too many to mention, usually featuring my mother not backing me up to the advantage of my brother or cousin or friends' kids. I recognise a lot of what people have put. Anyway here are some of mine:
My dad coming back from work unexpectedly early to hear me and my brother arguing. When he asked my mother who started it she said me - it wasn't - she did it to protect my brother which she usually did, thinking he'd be softer on me than my brother. I got a backhander for that so hard I hit the doorframe and fell to the floor.
My cousin staying over, 2 years older than me, ganging up on me with my brother who was the same age. I got sent to my bedroom for reacting. My mother's response - well I could hardly send your cousin to bed. No, but you could have told her to stop.
Ganging up on me with my grandmother to belittle me, or saying nothing in my defence when remarks were made about how stubborn, naughty, miserable, unhappy, awkward and unfriendly I was while my brother's nicknames from my nan were sausage, chick, sunshine - ooh isn't he so happy and easy going. I had 15 years of that - being the one that's not quite as good as the other.
A teacher one: accused of copying which I didn't do. The girl next to me and I got the same answers which were correct yet I was asked continually Did you cheat, I'll ask you again did you cheat, this is the fifth time, did you cheat, until I said yes to shut the bitch up.
Bought an ice cream by my mother's friend along with the other kids. She didn't ask what I wanted and got me chocolate which I don't like. Mother told me to not be so ungrateful and when I said I really don't like it she ate it so everyone had ice cream but me. Fucking lovely.
Brother got £500 for his 21st. I got a card. I was away at the time and had promises of we'll get you something when you're back. Never happened.
Loads of other stuff. I don't talk to them anymore. Don't miss them either but I miss a sense of family.
