Great Reddit comment:

Call your grandma/grandpa or even better pay them a visit and give them a hug. They won't be around forever and they will be just as happy to hear and see you as Betty was in this clip. One of the worst feelings is having just lost a family member and thinking about all those weekends where you had the time, but didn't call or visit...

If you don't have that opportunity, volunteer an hour or two at your local nursing home. You can really make a lonely old person's day. And think, today them, tomorrow (many, many tomorrows...) you.

Awesome video, good to see uplifting stuff.
