comic strip "Cathy"

Cathy and her Mom are sorting through large piles of photos:
Cathy: "Where was this picture taken, Mom?"
Mom: "I don't remember."
Cathy: "When was it?"
Mom: "I don't know."
Cathy: "How old was I?"
Mom: "I can't tell."
Cathy: "Who are all those other people?"
Mom: "I have no idea."
Cathy: "Should I throw it out?"
Mom (raising voice): "Throw it out?? NO! You can't throw it out!"
Cathy: "Tally so far: one for the memory book, 593 for the forget-ory book."
