My roommate in Austin would hide leftovers in the back of the fridge behind the pickle jars and then get mad when I 'stole' them. After 3 weeks of this, I put a whiteboard on the door and drew a little grid of what shelf was whose and where the 'off limits' zone started. It cost me $4 for a cheap magnetic board at Target, and honestly it ended the arguments cold. Has anyone else had to make a literal map just to keep peace over a shared fridge?
