The train has left the station

Even though the choice has been mine, and I have been adamant, once that train leaves the station and the opportunity is lost, does the consequence truly become clear.  I know this is what I have wanted all along and should be grateful that it is resolving itself.  But now, I am of course worried that I may have misjudged.  But this time, for once, I am going to leave well alone.

Standing firm, waving sadly and reluctantly.
