Because after all these years, you have dove into the nasty dumpsters, you have banged you head on the side of the big dumpter. It is called brain damage and a fractured skull. This injury cause hellucinations and bi-polar behavior. You also tend to let your brain waves float down into the gutter, evidence of your injuries are shown on both sides of your temple. The big knobs on both sides of your cranial cap. Hopefully, in time you will heal,, but to make sure there are no more massive injuries, do not dumpster dive, no more. Ya hear me??? Stop acting like a rat.
