I know I'm a violin/music geek because:

I named my pet turtle "Maxwell Turtellini Edison Paganini Ferrer the 3rd", Maxwell for the Beatle song "Maxwell's silver hammer" and "Paganini" for Niccolo Paganini....

When someone asks me for letters, like "hey, what letters are we answering on page 23?", I would sometimes respond "G D A and E".....

I sometimes experiment with my violin with some items available, like our school lab's beam balance, my sister's stethoscope, vibrations from my keyboard that used an organ option, etc.....

One habit of mine that always annoys my mother is tapping the table by rolling my fingers.....

When someone, like a friend, says something like "plucking the strings", i would sometimes correct him/her saying "pizzicato!"

would watch any movie that has a violin in it, sometimes would say something like "oh, cool, that's mozart's bla blah blah" when i hear a music in the movie....

play air conducting while listening to a piece....

Drew a small violin on my engineering subject's autocad project that was suposed to be a house floor plans with furnitures....

The list goes on.....
