You *know* you're a guitarist when...

[jmb-d]

...you open the dryer and find picks in the lint trap.

[Taso]

You can stick a thumbtack's tip into your finger and not feal anything.... (I get bored sometimes)

[Crazy Dave Miller]

You find yourself fingering actual, correct chords as you play air guitar while listening to music in your room.

[Crazy Dave Miller]

You scrap the air guitar, pick up your axe, and jam along.

[greybeard]

... the only G string you have in mind comes between D and B

....you try making chord progressions out of the roman numerals on clock faces

[purple]

...you have made up a lame excuse to not hang out with your friends just so you could stay home and play your guitar. It is so sad and kind of dorky, hope I am not alone on this one.

... the only action your concerned with is the height of your strings.

[Tucker]

Spotting bands that are miming becomes a precise art (nay - a science) rather than a jokey guessing game.

[TaylorR]

you own and play a guitar

[Alan Green]

When your neighbours say "we hear you playing your guitar sometimes".

Only sometimes? Geez - I need to ramp up the volume.

[Vic Lewis VL]

When your grandkids are learning the alphabet and you keep correcting them by putting "Bb" between A and B

[AcceptedOne]

rather than getting lyrics stuck in your head, riffs abound.

[Mike]

....when you start cutting your nails before they really need it.

....when you start picking your strings more often then your nose.

[Nils]

You morn the loss of a guitar more than a friend or family member....

[Celt]

...you see an attractive woman playing guitar and you think "Wow nice Martin D28"

[Nick]

How about when your significant other has to tell you the plate you are holding is hot.
