another one

so occasionally one of my friends younger siblings will
have their bar or bat mitzvah. to keep myself occupied
i bring my camera along. with my D90 in hand it is easy
for the guests to confuse me for the photographer. and
i love snapping candids. it's fun now, when i do it when
i feel like it. but i feel like if i had to do it for a living,
multiple times a weekend and for families i don't know
it wouldn't be as enjoyable. thoughts?
