That's a good question. I guess the answer depends when you ask it.
Daytimes, Monday to Friday, and Saturday mornings, I'm a school music teacher, zipping all over the county with my car crammed full of stuff; any combination of trumpet, guitar, ukulele, treble and descant recorder (at least they don't take up much room), djembe, samba whistle, repinique (that's a type of samba drum which is VERY LOUD), ocarina, bag of shakers, bag of claves, bag of boomwhackers, bag of bits of paper, mp3 player, laptop computer and a sound system. I don't claim to be an expert player on any of them, except maybe the sound system, but that doesn't stop me from having an absolute ball teaching them all! That leaves just about enough room for me, my handbag and a packed lunch.
Evenings, Monday to Friday, I'm a piano teacher, based at home.
Saturday afternoons, I'm a zombie. Not the living dead sort, just the zonked out sort.
Sundays, sometimes I'm an organist (1st and 5th Sundays).
I'm also a wife, mother, and a daughter.
For brief periods of time (late evenings, half terms, holidays), I'm also myself.
