lonely people

More and more I realize how lonely people are today.
In our world bustling with people, it seems there are so many scurrying about with a deep longing inside. There are homes filled with sadness and many people who lack purpose.
Generalizations perhaps, but observations from the past few months in Canada.

What is the deal?
Are our lives too full of work?
Are we too preoccupied with material things?
Are we "too busy" for meaningful relationships, or we don't know how to really form them anymore...as in our relationships are based on fluff rather than on substance?
Are we too busy thinking about ourselves and not busy enough thinking about and serving others?

Is it a God-sized hole in our hearts that we're cramming full with everything but God?

Or am I the only one who is observing this?
