Oh dear, the Christmas Lights are tangled again. See if you can follow the wires and find your way from the start of the lights to the plug,
If you would prefer the tangled lights maze bigger:
It is always hard to pack your Christmas lights away each year. You can put them back neatly in their box if you have it or wrap them around something so that they do not come out tangled the next year. I roll up bubble wrap and wind my lights around that.
