I wont even let my fellow band members touch my instruments (which is different for me cause I play 6), its normal. Dem non-musical folk just don't understand the mathematical understandings behind the sciences which make the sound waves which come out of any instrument which sometimes sounds like music. Everyone who doesn't play music in my old school thought that playing the guitar was a "joke" and "Anyone could play it". That is why I got an A+ for performance they got B's, C's and D's. Until they feel our hopes, fears and dreams they will never understand!!!
