lack of curiosity

overheard the other day between two old ladies in a restaurant:

"so does advertising really work?"

"yes, of course it does. why do you think we have tv?"

"what do you mean?"

"television is free because advertisers pay for the commercials on it."

"huh."

somehow this woman had managed to view thousands of hours of free entertainment without ever wondering where it came from. to be so oblivious is surely a gift.
