Describe a phase in life that was difficult to say goodbye to.

Not “was”, “is”

I guess I never really saw it from the perspective of saying goodbye to a phase of life. What is a phase? Do we get to a point in life where we have to say goodbye to a period of time? Your story is ever-unfolding and you are constantly adapting. What happened then isn’t over; nothing stopped, it’s merely changed.

Adolescence? High school? College? My first love? The move to the complete opposite side of the country? (I’m still in that “phase” of life.)

The question still begs to be answered, however. How do you describe the sensation of actively saying goodbye?
