The movie tells a story about a old man's adventure to look his grandson studying abroad in the US through his own perspective. While at last when the old man finally met his grandson and get to spend time with him, the scene draws back where he tries to call his grandson in front the mirror. Which leaves me a suspense of have he really reached to his grandson, or is it just his imagination doing the job because of the Alzheimer's? No matter what the answer is, when his grandson pick up the phone, we know his still being cared and loved.
