Emotionally drained...

I'm not that exceptionally good with people. That's what makes it so much harder when my job requires me to communicate with today's teenagers. Why are some of them so different from my generation? Where's the values? Or has the values changed with time? When they reach my age, will they be able to accept a nonchalant attitude, even rudeness, towards them from a teenager? Maybe they would. Afterall, everything changes. I need to reflect. I need to think about my mindset.
