Shower thoughts
We all have this terrible habit of leaving empty shampoo and soap bottles inside the shower months after using them. This guy complained to his girlfriend about taking out her empty goods from the shower because they take up too much room. Finally, he made up his mind to do it himself so that she might know how he felt about it.
Duct-tape her bottles to the wall as a way of delivering a message. This is undoubtedly petty, but it does not appear to be much of a punishment since it most likely took him longer to tape them to the wall than his girlfriend would takedown, and it isn’t much of a punishment. She’ll probably crack jokes and shake her head.
