Indecisive
I'm not sure whether the younger generations are more indecisive than previous generations or that it's just something that comes natural with being young.
It seems like my peers just seem to be indecisive majority of the time. It's unusual to see younger people commit to something; it's very unfortunate at times. I feel like it's all too common to hear "I'll possibly join you" or "If I have time, I'll..." And for Facebook events, there always seems to be more "Maybe" response than any other response. It makes planning events for the proper number of people nearly impossible when no one commits in attending. We have come to take advantage of the flexibility that comes with instant communicate but I don't think it should affect our commitments. This really interconnects with the self-responsibility that many lack.
And that's not even mentioning defining relationships.
Maybe being decisive comes with age and knowing what you really want out of something.
