Calvin and Hobbes by Bill Watterson for March 05, 1991
Calvin: I just saw a commercial for a luxury cruise. How come we don't ever go on vacations like that? Dad: Vacations are all just a matter of comparison. Calvin: Huh? Dad: We spend a week in cold, uncomfortable tents each year so living here the rest of the time seems like a luxury cruise. If your trips are unpleasant, your whole life is a vacation! Calvin: Please tell me I'm adopted.
