for some reason, i can't justify spending money on lunch, but i can justify spending it on an antique camera in mint condition. but i got a good deal so i feel somewhat like the thrifty shopper today. they had a case for a great pin-hole camera, but the lady couldn't find the actual camera and guessed that it had been shop-lifted. it's a shame, cause i was going to buy it for you. don't worry, it was real inexpensive. but the one i got is fetching four times as much on ebay as what i bought it for.
