Do they? Is social media being used in morning classes to plan lunch? Will a socially isolated student even have friends? I haven't been in school for many years so I don't know the social dynamic but it isn't hard to imagine.
Do you really think kids are “planning lunch” over social media, when they sit at the same tables every day? And the cafeteria is providing it? Sounds like you’re grasping at straws to make it seem relevant.
The kids here communicate via imessage and rarely during class.
