Goodbyes eh!

There are people who come into our lives
sometimes they leave,
sometimes they say they want to remain.
Sometimes they don't know what they want.
The hardest thing to know is if we should let them go,
or hold on.
Can we hold on to tightly or to loosely.
Can we ever really go back or does doubt
of what happened that drove friends apart
reamin so close we never see beyond it
again.
Should we let go or keep trying?
