I always thought that my husband and his sister always had a very special relationship between them. I always felt it was very different and a bit too much for my taste. But I though it was only me until I've came to watch this video made when my husband's sister came to stay at my our place after I've had a surgery and had to stay in the hospital for a week. She came mostly to take cake of my son but for my surprise she also took care of my husband, her brother, and I'm pretty sure it wasn't the first time they did it.
