My (26f) boyfriend (27m) went on a trip with his friends for a week. He called me on the third day of his trip and asked me if I knew how to do laundry and if I knew the temperature settings for different clothes

My boyfriend and I live together. He went on a trip with his friends for a week, he left 3 days ago.<br><br>He called me today and asked me if I knew how to do laundry, if I knew what temperature settings to use for different clothes and what spin settings. He said he forgot to buy laundry detergent so I should buy some for him.<br><br>It feels like he knows I know these things, and I obviously do know. I am very capable of doing household chores, especially laundry. I do cook and clean and I never ask my previous boyfriend how to cook an egg or boil water.<br><br>Is this a valid reason to think he thinks I am inept in adult responsibilities?<br><br>Or am I just being stupid and PMSing?
