Better to live and fight another day.
Indeed.
As long as you do fight.
Well, do us all a favor... If you ever find yourself in a foxhole and decide it’s time to leave so you can live to fight another day, do your foxhole mate a favor: Let him know BEFORE you leave so he can make an informed decision.
There’s nothing worse than dying a needless, naive martyr’s death trying to defend a ghost in the night who turned out to be wiser than you were at the moment. :)
