Yau-yau has a doting grandfather who is charged with school pick-ups, a routine that often comes complete with toys and treats. But Grandpa has become forgetful lately. In fact, he has left doors unlocked and was found wandering streets, disorientated and lost, worrying signs that raise a red flag about a particular condition that Yau-yau’s mother has dealt with up close and personal – Alzheimer’s. Grandpa responds in defensive denial until one day he breaks a daily pattern and begins a spiralling deterioration that Yau-yau is still too young to comprehend.
