Forget snooping in the medicine cabinet (where you shouldn’t actually ever keep medicine anyway because the humidity in a bathroom is bad for storage conditions), if you want to get to know someone, check out what they store in their fridge. One of the hardest things about moving in with another person, be it a friend or a significant other, is figuring out when to protest or give in on their strange food storage habits. Does he put peanut butter in the fridge while she prefers it in the pantry? Uh oh. That could spell trouble. Many of our food storage habits are learned from our parents, so when they are challenged, we tend to get defensive about our choices.
