It's a definitely a sign of maturity to be comfortable in uncomfortable situations. And it looks like that lesson is being learned quickly by this boy whose mom clearly said, "I'm sure there will be lots of other boys at Brittney's birthday party!" He really handles it well, even feigning interest in what I guess is One Direction karaoke? Sorry, I tried to Shazam this and it just came up as "aggressive mumbling."
Next he hit up a few baby showers. Just kinda hopping around.
