Programming is pervy.

Consider X11, the windowing system used by eunuchs. In it, windows are either InputOnly or InputOutput. Windows are organized hierarchically, i.e. so that they have a parent window, sibling windows and possibly child windows.

The perviness comes in when one considers sibling windows, i.e. brothers and sisters. That's right, sister windows are InputOnly.
