You plot your revenge
It's a small village, so there's not a lot of places to hide around here, but you manage to crawl down into the deepest, darkest hole you can. You spend a day recovering, mostly just sitting around, drinking beer from a straw and plotting. They are going all fucking pay up. Big time.
That night, you take your car boat jalopy on a midnight cruise, getting up to fifty miles an hour on the water, then killing the engine, silently floating for a long time. You drift along the shore, looking for dude's car or boat... where is he? Must be around here somewhere. Ah-ha! You find his boat is docked at the little blackwood floating flotel — a flotel is like a motel but its floating service where you can rent a room — and drift by, getting close, so close you can smell your ex-girlfriend's scent through an open window.
Time to kick this revenge into gear: you back way off and speed toward the flotel at full throttle. Right before it impacts, you bail out of side, diving hard into the water. Your jalopy crashes through wall that those vile curs are fucking behind, exploding in a great fireball. Both of them are killed instantly!
After they fish you out of the water, there are questions. You claim you couldn't see the flotel, that it wasn't your fault, and, unbelievably, your lie holds up in court. The floating building had no lights at all. Only locals knew about it. Your new enemies are dead and you are unhurt. Car insurance even pays for new ride!
