Graduation Advice

At a recent high school graduation I attended, the principal concluded his grad speech with these wise words, "Get off your phones; live your lives." I thought this was brilliant; however, as he stated above, I noticed many surrounding me ON THEIR PHONES having completely unrelated conversations, watching videos, playing video games, etc. Some of the kids attending had iPads and full-cover headsets, so they we completely tuned out of the speeches and zoned out on stupid video games. It's frightening--and dangerous.
