He used to hang it on the fridge, but that changed. Now he prefers to have it downstairs on a computer desk, where he often relaxes away from the rest of the family while he plays video games, listens to music, and watches YouTube videos -- often at the same time!
I looked at this calendar more closely and discovered Isaac had grabbed a pencil and filled in most of the weekends with one of his favorite activities, listening to the country station, K98.5 FM.
Isaac needs a reminder to brush his teeth. He might need to check the calendar to see when his class is visiting the public library. I can't think of any occasion when he'd consult the calendar before turning on the radio.
He plays the music 24/7. It's a non-stop country music festival in our home unless I sneak into his bedroom late at night and turn off his iPad while he's sleeping.
I guess he just likes to make plans.
