Cell phones are certainly not necessary, and "but I'm from the digital age, this is what everyone in my generation is doing!" isn't a very good excuse for being hooked on a glowing screen 24/7. In the 1960s every teen of the times was tripping on acid and running off to find themselves in communes and love buses. It was a fad, there was no excuse for it, and it passed, just like I think that this generation's "cell phones are necessary for socialization" fad will eventually pass. What will it bring afterward? I don't even want to know, but I'll keep my fingers crossed and hope that it isn't anything else digital.
