In the video, which was shot by the teen named Andrew as he was sitting on the toilet of a Chik-Fil-A restroom, you can see a small child peek under the stall inquisitively. Without asking, the kid then crawls under the stall door, asks the teen what his name is, and proceeds to explain that he just wants someone to help hold him up so he can wash his hands.
Understandably bewildered and not in any condition to get up and help at that very moment, Andrew doesn't flip out but rather nervously laughs and tells the kid that he should get his mom, who's just outside, to help him. Without responding, the kid unlocks the stall door and walks out, then tells Andrew to lock the door behind him. So evidently he does understand the value of privacy?
All in all, you have to hand it to Andrew for being rather chill about it all. In fact, the kid's dad replied to the video he posted on Twitter, apologizing profusely for his "very, very friendly" son, to which Andrew responded like the cool cat that he is.
