typically during every 10's (10, 20, 30..).
so when you arrive in the station at 6:28 and see the train just leave,
it's frustrating.
but then I have to get myself together.
if I'm going to morning service for God,
I should have the assurance that God will lead me there at the proper time.
so there's no reason for me to be frustrated--
doing so would only mean that I'm questioning His abilities.
