This Canadian short is really good. 

Here is the official review:

JUST SMILE AND NOD is a comedy about a 10-year old Eurasian boy, Matt Wilton, (Brando Keeler)
who dislikes visiting his Chinese Grandpa (Colin Foo) because of the language barrier.

To Matt, Grandpa is an old-fashioned traditionalist who “doesn't even own a computer”.

After his parents pass the buck, Matt is stuck with dropping in on Grandpa for his birthday.

But the tables are turned when we finally meet groovy Grandpa, and it's Matt who can't keep up.
