Hi, 赟飞 柴.
Maybe you should have slept in the bigger bed on where your parents slept. I thought parents should use bigger and better bed and room, so I happened to give the smaller bed (full size) to your couple. However, it could be better if you and your parents switched the bed, since you are physically a big man. Oh well, it happened! Sorry for that. Your bed (full size) is mostly used by a single person who come together with friend's couple or by a single parent who come together with their grown up children who are married.
