Then I went with LargeHead, Starky, and Andy to the mall. We drank some pearl tea, ate pizza, and did some last minute shopping (and I mean last minute since we were the last customer in the supermarket).
I only managed to get 2 milks that both weren't for me anyways, and didn't manage to buy soap for myself and pita bread for my housemate.
Then my housemate sort of shouted at me for not bringing her pita bread which she needed for dinner (I brought back the milk at like 10.30 PM) and she was waiting all along.
She meant it as a joke maybe but anyway I was tired so I gave her the milk and said "Next time, tell me if you're eating it for dinner. Here's your milk. I'll give you the change later." in a very annoyed way and went to my room.
I was thinking, first she didn't tell me it was for dinner, then I felt that I was under no obligation to just obey her and get shouted at if I didn't bring back her requests.
We talked afterwards casually, but there was this hanging feeling perhaps it was guilt that I couldn't bring back her dinner after all.
