Keep that away from me

I'm supposed to be much more pressed to concentrate on mugging after the completion of my programming project (whatever, the deadline was extended to 8 December). But it doesn't help to have a Yamaha organ sitting right in front of me NOW. Apparently my sis is serious about picking it up, and it's creating a bout of chaos in my home, after that absent-minded darling plugged the two-pinned adaptor upside down on the extension bar. And she's supposed to be a Physics student acing in the subject. Oh well. Looks like I'm banished to the school library for my pre-exam mugging for the entire week.
