> Which is more social than either of the other hobbies you mentioned.
The girl in TFA just dumps the snapchats she's sent, flicking through them just to be rid of them. She's not being social, she's just incrementing a counter to boast about. Well, unless you're calling the boasting the social part, I guess, but I wouldn't say that that was more social than learning a musical instrument.
Which is more social than either of the other hobbies you mentioned. How is it shallow and void of any meaning?
