Although the water from my kitchen and bathroom sinks is the same, I never drink from the bathroom sink. What are some irrational behaviors you have?

Every night before bed, I walk across my house to the kitchen sink to fill up my water bottle. The bathroom sink is 5 feet from my bedroom door, but I never drink from it because it's the bathroom sink. I know the water comes from the same place, but it just feels weird. Does anyone else have completely irrational behaviors like this?
