He is sure to wake up the next day, and want to run away. He'll grab his Ducky backpack, slam the screen door behind him, and head out into the big, wide world (er, the outside perimeter of his house, while being followed closely by his mom who is armed with the camera).
He'll look up and see that his big sister on the roof with Daddy, helping him clean leaves from the gutters. He'll decide that he needs to have his own fun adventures.
So he'll head over to the landlord's house (aka Grandma Joan's) for a visit, even though he is only wearing his diaper.
Grandma Joan will think it's so fun that he has come for a visit, she'll secretly tuck a few pecan sandies in one of the pockets of his Ducky backpack, and send him on his way.
Matthew will later discover the pecan sandies, forget entirely about the bad haircut, and decide that home isn't so bad, after all.
