The internal weather report is another great tool. Have the friend who helped you with the previous exercise pencil in the weather icons for each activity on his or her path through the day.
For extra credit, you may have the person do a three- panel cartoon for each time he or she engages in the activity you're measuring.
Put it all together, and what have you got? Certainly a lot more than you would have if you'd sat the person down and asked, 'Tell me about your experience with your breakfast cereal.'
