my sister is a certified piece of shit AMA
How old is she?
18, same as myself. Triplets.
Triplets, wow.
Anyway, 18 is a good answer. As much as I disagree with Mrebo framing his experience as worse and therefore more legitimate than yours, I will say if you have a shit parent, the chances of them changing and becoming not shitty is very low, whereas with a sibling (especially someone who’s only now entering adulthood), there’s still a lot of time for them to grow and become less of a shit.
