You should alternate through all the possible combinations before repeating any.
L sock, R sock, L shoe, R shoe
L sock, R sock, R shoe, L shoe
R sock, L sock, L shoe, R shoe
R sock, L sock, R shoe, L shoe
L sock, L shoe, R sock, R shoe
R sock, R shoe, L sock, L shoe
Then shuffle the order of the sequences. Until you get all the possible orders. That’s a bit more involved.
Alternatively, roll a die to determine which sequence to use each day:
1. L sock, R sock, L shoe, R shoe
2. L sock, R sock, R shoe, L shoe
3. R sock, L sock, L shoe, R shoe
4. R sock, L sock, R shoe, L shoe
5. L sock, L shoe, R sock, R shoe
6. R sock, R shoe, L sock, L shoe
At some point, you may discover that you have ceased to care, or you have discovered the order you like best, or that you are enjoying the game. All results are good. Unless your romantic partner decides you are insane for doing this, and leaves you. But if it makes you happy, maybe you’re better off without them.
