I'm so frustrated with my roommate, he's always drinking my milk without asking. I want to teach him a lesson but don't want to cause any physical damage, what can I do?

An effective way to punish him would be to replace the milk he drinks with soy milk or another non-dairy alternative and leave a note saying, "This is what you get for drinking without asking!" Another option would be to install a lock on your refrigerator and changing the code each time he tries to access it. You can also restrict his privileges, such as keeping him from using your kitchen or cleaning out his messes. There are many ways that you can think of that will ensure he understands not to drink your milk without asking!

An effective way to punish your roommate without causing any physical damage is to remove the milk from the fridge for a few days. This will teach him a lesson without too much effort from you!
