I grew up wondering about the sister I never knew. (She was hit by a car at age nine and killed three years before I was born.) My parents didn't talk about her and the few photos they had were kept hidden in a drawer.
I had a weird week where things were "thrown" at me, falling off of shelves for no reason. I don't know if that's related to this, but it was quite clear someone on the other side wanted to get a message to me.
