My youngest son is a rock star, or at least he thinks he is after a $4 purchase at the Autumn Street Fair ended up being one of the best investments I’ve ever made.Like many kids his age, Henry, now 10, tends to find his favorite thing and go overboard with it. I guess we all had our favorite toy or favorite thing growing up so obsessing is somewhat normal as a kid. Like Linus’ blanket in the Peanuts cartoon, we all have something we just have to have, even as adults.For Henry, his obsession as of late has been the “Five Nights at Freddy’s” game.
