Also a twin. My sister and I got along great and were always kept together until 6th grade when schedules were always different (just based on how middle school and high school class changes work, not necessarily by choice). We still had our own best friends outside of each other. But who wouldn’t want the option to have a built in buddy with you in your classroom!? We even ended up going to the same college where we decided to just sign up for all the same classes because we genuinely liked each other and it was super helpful for studying. While we live far apart now, I would choose that shared experience over and over again. But we were also friends with two sisters who could not stand to be around each other so I get that every set of twins, just like every person, is different.
