Haha, @Dream, vampire high-five!
I have no idea who I could've inherited the sun sensitivity from, my mom absolutely loves being in strong sunlight for extended time. Idk about my dad tbh. I should ask him. But I'll probably forget xD
I just avoid going out for long when it's sunny. And at the same time I try to go out for just a little bit when it's sunny because vitamin D deficiency
I remember in my teen years I would mostly wear long sleeves and pants no matter the weather because 1, I was kinda goth-like or whatever and 2, I was super uncomfortable with my own body, and showing bare skin was a no-no in my brain.
