He doesn't pay attention. His eyes go blank when I talk to him of things that he finds boring. He wants to do things his way. I am glad I do not live with him or I think I would go nuts. However as he passes by and drops in from time to time, I must still put up with chairs being placed just so, convenient for him, but in my way, or other such things. He does not want to listen to my arguments for something different, so I put up with him until he leaves again.
Then Gollum will suddenly appear, with some project he has been working on and asks my opinion. I am not sure why he wants it, as most times he is not interested in what I think. Perhaps he is just excited about what he is doing, and in spite of him he needs to share that excitement with another. Perhaps my opinion still does not count, and this is just one way to get some kind of approval or compliment. Perhaps it makes him feel generous to let me voice an opinion on some subject of his choosing.
But how does one politely decline the honour? I am not interested in voicing my opinion on anything to him, if my opinion has no worth in more important issues.
