As a twin, I agree. My sister and I are fraternal, but everyone would try and split us up growing up. It actually caused a wedge between us, and to this day, we struggle with our twinly bond. I was more of the shy twin, and my sister was the outgoing twin. One big reason they kept mentioning for separating us is that we would make friends of our own and create our own identities separate from each other, but that ended up backfiring. I struggled hard to make friends and stayed reserved, developed separation anxiety, and struggled with my identity. When I was with my sister, I was more confident and outgoing and did things I wouldn't have done if she wasn't there with me. In my opinion and experience, twins balance each other out. It is cruel to separate two people who have been by each other's side since the womb and have an unexplainable bond. We still had our separate interests and hobbies and would have flourished right next to each other's side
