Greg Heffley has always been in a hurry to grow up. Being older means you can live alone, eat whatever you want for dinner and don't have to share with your brothers. PERFECT. At least, that's what Greg thought, but it turns out there's a lot more to growing up like dealing with boy/girl dances, increased responsibilities and awkward changes.On top of all this, he's fighting with this best friend Rowley, and is being dragged to his uncle's FIFTH wedding. Surely there's more to growing up than THIS?
