Time Machine Trauma

I hand over the bank notes - the box I take home A flat pack tech gadget wrapped up in white foam I peel open the packing - my keenness obscene To lay out and make up my new time machine I look at the pieces - feel ill and confused Some look rather old - some look quite misused The box should be mint - instead it's been torn The branding is tired - the printing is worn The instruction's in Swedish - the picture's unclear This thing-gummy-doodah - screw there or glue here? A few bits left over - a few bits amiss I'm losing my patience along with my wits It doesn't look perfect - I hope it will do I sit in the cockpit - time travel debut I dial in year zero - an interesting time I arrive at last week - a paradox crime In anger and sadness I pack the gizmo I take back my purchase to reclaim my dough With box under arm I storm into the shop My future receipt slammed down counter top There isn't a problem - my money's returned They know that in practice it's really a loan The box is repaired and returned to the shelf And next week they sell to my good future self Rewritten 16th April 2017 Entry to "Jamie's interesting contest 2 - travel back in time topic"
