There is 11 years difference between my sister and I. I consider myself an only child and one day I asked her if she felt the same about herself and she agreed. By the time my sister was born, I was almost a teen. I was introverted, so I kept to myself pretty much. I left to go to college at 17, so she was only 6 years old. So her memories began around that time. I haven’t heard of anyone else having the same mindset-2 kids feeling like the “only child”. My sister and I are exact opposites. She grew up extroverted. We had opposite childhoods, so it’s understandable.
Lately, we have gotten closer, due to various life events, and I am so grateful for this. I have wanted to hang out with her forever. I think she and I could actually live together! I think it would be a hoot. Maybe she would introduce me to her friends as her “crazy brother”. LOL
