At least showering indicates the person is clean. It's better than threads about cats, dogs, or worse, what I had for dinner/drinks/weed tonight. Showers are great fonts of inspiration. Some people become opera stars - do you object to people feeling inspired?

Also, on this board, we encourage threads about mums, dads, grandparents other relatives, especially if they have a victory over adversity. We also have threads asking for some prayer - in the same vein.

So your point is?

Is it because people do not wear bathing costumes in the shower, so that your dirty mind start thinking about their private parts? Do you wear a tuxedo to bed? Maybe the people in your dreams laugh at your pyjamas as you attend an important black-tie event?

Also did you think that mods care about your ghostbuster outfit hanging on your door?
