Diary Of A Wimpy Kid: Old School

I really don't understand why Mom thinks we need to go BACKWARDS, anyway. From what I can tell, the old days weren't that much fun. Life was better in the old days. Or was it? That's the question Greg Heffley is asking as his town voluntarily unplugs and goes electronics-free. But modern life has its conveniences, and Greg isn't cut out for an old-fashioned world. With tension building inside and outside the Heffley home, will Greg find a way to survive? Or is going 'old school' just too hard for a kid like Greg?
