This is your "feel good" video for Christmas morning.
And here is the sequel, filmed 10 weeks later.
From the filmmaker's comments at Reddit:
A lot of people asking how to help. Here is a list of organisations based in Uganda helping the deaf. One of my favorites, and for which it's very easy to donate to, is called Sign Health Uganda. The organisation which set up the course for Patrick is called UNAD - their donate link is broken so you have to email them directly.
