When I was growing up, my Grandmother lived with us every summer. Because it was just a few months out of the year, and because we didn't have an extra bedroom or bed, we shared a bed. The only downside of this is that my grandma snored, and I would kick her to get her to stop. My grandma was awesome and never complained.
Once I was an adult and realized what a brat I had been, I apologized to her.
