signs you've been in san francisco too long

in no particular order

you congratulate anyone who is paying less than 50% of their salary (pretax) to rent.

you forget what iceberg lettuce is, and when confronted by it, recoil with horror.

you are used to being chastised for not bringing your reusable shopping bag.

you see an iPhone 4 and think it's "quaint."

you don't balk at making reservations two (or more) months in advance.

you are unfazed by the crazy person ranting + raving on the bus, and just hope he gets off soon.

you walk quickly, even up the hills, even when people visit. you are confused when they need to stop midway.
