Sisterhood, part one of an infinite (I'm sure!) series

My big sister and I have always shared a bunk-bed. Even when I was married, my husband and I slept in the bottom bunk with an open spot for her above us. She wasn't there the night I forced myself onto his dying body, but she testified against me in the ward anyway. In the end, she took my share of the inheritance, but I guess she was just looking out for her baby sister and her allegedly frivolous spending.
