This is when you invade the playgrounds of others. OWN THEIR SANDBOXES.

Or, set up booby traps so that anyone who comes into your room may be in peril. Try a camera dangling from the ceiling above your door too, so you can have some evidence in case anyone tries stealing, fondling you in your sleep or something similarly likely. Because you know it may happen.

Go conquer their playgrounds.

You're Amazing.
