'for better or for worse...' I'd guess the average person who's taken those vows probably does not give much thought to what that can mean. I know I didn't. For my sister-in-law, in part it means forsaking the proverbial shared wedding bed. She pulls a mattress out and slaps it on the floor, half in the room and half in the hallway to sleep next to the bed of my brother. There she sleeps until awoken in the night by her husband who is experiencing a pain spike and needs some medication to alleviate it.
