random wedding guest (older woman, probably in her 50s): how many pictures have you taken at the wedding so far?
me: ummm, probably close to 400 now.
rwg: wow! i ran out of memory. how much do you have?
me: (mentally counting the memory i have on hand) probably about 10 GB.
rwg: oh! my goodness! i ran out of memory and i thought 256MB was a lot!
