"Drinking alone was definitely terrible!" the man wrote in his YouTube video description.

He continued:

I put an extra glass in front of me and poured Soju (the most popular alcoholic drink in his native country) into it... I cheered by myself with the glass of Soju, as though there was someone in front of me... the secret of taste of alcohol totally depends on existence of partner. This is why I made this robot.

Don't feel bad for Park, though. He most likely didn't celebrate Christmas 2015 alone, since Art Center Nabi (an art museum in Seoul) supported his little robotics project. The bad news is that Drinky isn't being mass produced, so you'd have to find (or build!) your own drinking buddy.
