SO MUCH commerce surrounds a day at school. You disrupt that along with everything else.

If Mom doesn’t have to go to work, she doesn’t have to stop for that Starbucks on the way in and fill the gas tank. She doesn’t have to pay to park or feed the meter. If she’s not taking the kid to school, she doesn’t have to drop them off early at early day care and doesn’t have to give them lunch money to spend. If you’re not at work, you wouldn’t eat that shitty Subway at lunch and wouldn’t have to go to that gathering at TGI Fridays after work. Little things that add up. Point is to show them that there is a light switch. You turn it off for a day to tell them you could turn it off longer if needed .
