At my house the rules are "no tops allowed" but whenever I visit my friend Sarah the rules are a little different. I've always noticed it to be chilly in her house.
There is a rule as to what you can wear at the dinner table, that being only a plug. My wife failed to inform her best friend that when she invited her over for dinner one evening.
My little sister invited her friends over to watch the Bachelorette the other day. House rules are if a lady in the house wants control of the TV, she must please whoever has the remote. It took a couple hours, but I was finally satisfied.
