I weigh upon your brow at night, Nibble and gnaw and tug and bite, Things that won't but maybe might, Certainty nowhere in sight, Perchance, perhaps, maybe or not, In-between the either caught, Wonder, worry, fretful thought, Stuck halfway from ought to naught Branching bools depend on me, You call my name to say we'll see, Notions flying fancy free, Won't decide which way to be Kipling called on me in verse, I concern the risk averse, Just two letters, simple, terse, I balance options, better, worse Patience worn thin? Go on, punch me in.
