Answer :
I believe the greatest challenge our generation is facing would be socializing. It seems crazy to think that would be our challenge, considering we do it all the time from our phones and devices. However, I believe the main problem is socializing face-to-face; We find difficulty looking up from our phones and saying "Hi!" to people on the street or ordering a cup of coffee. For the most part, I believe we have become so used to a new way of speaking that we havent fully mastered the "old way" of speaking. In a sense, we simply arent used to it. This leaves much of our generation "socially immature" when it comes to speaking in person, especially to older generations. In other words, I believe the greatest challenge facing or generation would be our range of social skills.
Hopefully this helps!
