My brothers got back from being at uni and I was talking to him about it. He went on to say that I was the biggest thing that he missed from home and that he thinks about me all the time. He then showed me a picture display that he'd made of pictures of me and him.
I feel really bad though because although I do love him, I don't think about him all the time. Maybe I'm being silly about it but I feel really terrible about it, AIBU.
