You are a musician. You're a Harvard student, majoring in music, and you've spent the past six months making your pocket change playing here on the platform. You've developed a good rapport with the T bureaucracy, and they now wave through your applications to play there without even hassling you any more. You're skilled at a number of instruments, ranging from oboe to piano, but you have to admit that your first love is still the guitar.
An exquisite guitar (Good Guitar) -- This is a really classy guitar. It's made by Martin, and it's not a bottom-of-the-line Martin, either. The soundboard is laminated with inlays of three different woods, and the frets are mother-of-pearl. Even a non-musician can tell that this is an instrument to be reckoned with.
A guitar case (Guitar Case) -- A plain black leatherette case, suitable for carrying an acoustic guitar. Slightly padded on the inside, with black furry stuff.
T musician's license (T Musician License) -- An ornate form, apparently from the office of the MBTA, licensing the bearer to play music in the stations of the T system. There is legalese all over it, warning that infractions of T rules can and will constitute grounds for revocation of the license.
A T Token (T Token) -- A dull brass-colored coin with a picture of a train on it. T tokens cost one dollar, and allow you entry into the subway. Once in the subway, you can go almost anywhere in Boston.
Skilled musician (Skilled Musician) -- This person is a musician of surpassing talent. Even people who profess to have a tin ear pause to listen for a minute, and those who appreciate music are likely to get badly distracted when he is playing. Regardless of genre, he always seems to hit all the right notes, and play with passion and feeling.
Can ride skateboards (Skateboard Riding) -- This person is a skilled skateboard rider, capable of making the board race along just where he wants. Can ride the board down stairs with ease, do jumps, and things like that.
