My best friend as a child had precocious puberty, started her period at 7 or 8. I didn’t understand her interests in boys/boy bands and within a few years we were worlds apart and I just wanted my first bra while she was thinking about sex and smoking pot. She got pregnant as a very young teenager and had an abortion that turned her evangelical so we’ve drifted apart. 

Another girl I lived next to as an adult faced the same issues and it seemed to cause her anger issues, I had to be very careful letting my daughter play with her because she could be aggressive and mean sometimes. 

These are just 2 examples of cis kids who could have benefited by puberty blockers delaying their onset of puberty, and I’m just one person. I could come up with more. I’m sure everyone knows someone like this and never even knew the situation.

...Huh. I think the reason for the way a few of my peers acted in grade school just clicked. I didn't understand at all how the fuck a middle-schooler was into smoking pot and sucking dick when I was nowhere near those ideas, but precocious puberty with poor parental support makes perfect sense, honestly.
