A Reason, A Season, A Lifetime

People enter your life and they leave.  Their purpose in your life can usually be attributed to a reason, a season or a lifetime.  We sometimes put people into the wrong category with the line of thinking and have to make adjustments based on their actions.  I have/had a friend who I thought feel into the lifetime category.  Career moves separated us physically but we keep in touch via calls, emails and texts.  It's been a few months since I have heard from this friend.  I've tried reaching out but have yet to get a response.  I guess my lifetime friend was actually there to just get me through a season or I was there to get her through one.
