Living with Bob and "Al"

Sheri kind of lost her patience yesterday, she feels terrible about it. She has been trying to get organized in this tiny but cozy house she rented. Bob wanted to help so they were sorting boxes together (mostly Bob watching Sheri work) They had been working for several hours, it was a very slow process. Sheri had just emptied a rather large awkward box that had a lot of loose things a the bottom. She needed to go through the assorted stuff so she asked Bob to get a zip lock bag. So she spoke slowly and specifically, asking Bob to get a zip lock back from on top of the microwave. Sheri already had the awkward box up in the air braced between her knee and the wall. The kitchen is five steps from where they were, the microwave six. "Al" could not find the microwave or the zip lock bags. After several minutes of Sheri trying to re-direct him with the box still up in the air, she got frustrated and she finally had to drop the box and retrieve the bag herself. She was tired and irritated that "Al" could not perform such a simple task. Bob sensed her disappointment,and said "is there something else I can do to help?" Sheri was embarrassed by her behavior, she knows it is not his fault, but the reality is there is just not much Bob can do to help. Sheri hates this disease.
