Beto won't wear a guayabera to the wedding. Nope! Nunca! Not going to happen! Beto tries his best to rid himself of the traditional Mexican wedding shirt his Mami gave him. He even gets help from his dog Lupe, but the shirt ends up back on his bed each time with notes from Mami, who becomes increasingly frustrated with Beto. Mami insists that Beto attend the wedding, and wear the shirt, because--after all--it's her wedding! Beto has to accept the fact that Mami is getting remarried and that she wants him to wear the shirt, which is part of his heritage.This book comes with a free Reader's Guide for children.
