"What should I do, grandpa Ger?"Being unable to train to his heart's content, Zax helped his two grandpas and two grandmas to set up the birthday deco...ation. It was weird, papering your own birthday. Usually loved ones were solely responsible for this job, but since Zax did not go to school his mom sent him to help and also spend some time with his grandparents."Nothing, Zaxy, Laylen sent you hear because we rarely see you this days. Let your grandpas arrange everything. Sit on a chair and tell. " So does this mean that Karen and I should be checking to see if you have someone in here every time we come home?"
