It could be that they had been together all day and were talking all day and were just taking a break to check their messages and stuff, I don't know.. BUT.. It is more likely that it's just a part of the evolution of so many people into their computers and away from reality.. Before long I predict many if not most people will be glued into their virtual reality headsets and in their own virtual worlds in a way in which most people seem to be now with their phones..

In time, as the technology increases.. I think this will just get worse and we will pretty much have people living in their computers, sort of like batteries in the Matrix. Heh.
