I buy almond milk because I like the taste. Things came to a head when the almond milk was empty again. To catch him in the act, OP purchased a gallon of regular dairy milk, then poured it into the almond milk container to see what would happen. I drank what was left of my almond milk and refilled the gallon with the one I bought. It’s a little tense rn and my roommate told me R is trying to convince him to agree to kick me out.
