premise: Robin had been working on bringing two of every meal out the kitchen door ever since Barney had arrived . She was definitely starting to feel taxed because moral support was one thing . Bringing alcohol , conversation , entertainment and food ? That was something else entirely but it was n't like she was going to abandon him or make Marshall do it all . Why would Robin take on so many things to do when it 's so taxing ?
hypothesis: Because Robin felt the responsibility but not duty to do it herself .
