I'll go!
In Middle School, I was on my way home and was waiting for my mom to pick me up at a fast food place. These two boys came along (I know, red flag immediately) and grabbed my water bottle, threw it, broke a rose I found for my mother, out of instinct I yelled, "You're an a$$hole." They then proceeded to act surprised that I retaliated and the whole experience was traumatizing for middle school me, I called my mom crying after they left and when she picked me up she agreed that the next time I saw them or any person did that: she'd yell at them if they were there, I'd get to yell at them and we'd both get pissed together.
I'd never told my mother anything like that until this happened, because I was terrified she wouldn't believe me or she wouldn't care. Her genuinely feeling sympathy for me and actually standing up for me unlocked a trust I didn't know I could have with her, of course right now I've had enough of boys (every year of my life leading up to that experience I'd been basically harassed by boys) I'm now a lesbian asexual, and I'm proud of it, but I do have a genuine anxiety around boys now.
