it is normal, as a human being we’ve been derailed as long as we know that no matter how bad we’ve been slipped away from the right path…..we’ll come back! there’s no point on looking back,  its doesn’t help much actually.  Apparently we have to look forward, enjoy the view and enjoy the company….but remember you might been derailed again,  its ok! but just remember to come back. Ultimately,  we’re heading to the same destination…aren’t we?
