Reddit, we never have forks because our crappy roommates leave them in their room. What should we do?

They're a couple. They share a bedroom. The eat all their meals in there. Yeah, it's a little gross. And we never have any clean fucking forks in the kitchen. There are 16 forks somewhere in the house. We have a dishwasher, for christsakes.

First it was scissors. All our scissors ended up down there.

The two of them are nice as ever to our faces; "Oh, we're so flaky, yeah, we'll bring them back up."

The silverware is half ours and half theirs. Which means that 7 forks of our are currently MIA. My idea is to just collect up all our forks and horde them so that we always have them when we need them. My SO suggests an even more passive-aggressive route: re-stock the silverware drawer with plastic-ware.

What do you say?
