Sadly, no chemical alteration is in effective. That is how my mind works!
Like when someone is going on and on and on about something you don't care about. My mind often wanders to such topics like "Would they notice if I piddled on their foot?"
Or back in college, there was construction on campus and there was a small articulated wheel loader parked there. Other engineers were talking about the construction, the design, blah blah. I was thinking "I bet I can get that into the university president's office on the second floor..." I figured I could too because of the wide staircase to the second floor that was on a shallow angle...
