Is it laziness or what?

My husband has this habit of bringing a glass or a bottle of water, tea, juice, or whatever beverage he is drinking at that time, in our bedroom. He has this small, three layer shelf beside his bed where he puts his stuff. Often times he brings the glass or cup of his drink, and place it in his shelf without bringing it out to the kitchen after using it, until it piles up. I have once told him about this, particularly at one incident when I was feeling irritated, and in total bad mood for unexplainable reason. After I told him, "Is it hard for you to pick up after yourself once in a while?", he responded negatively and a huge fight broke out between us. His opinion is that, since I am at home all the time, does not have a job yet, and mostly doing nothing big at home, that doing this small things after his hard day at work should not irate me. Yes, I know that some of you might think that he has a point, but for me it feels like contempt. I know that I have not done any meaningful thing these past few months while staying at home, but I do have a lot of ideas in my head. All I want is to have the time to think about my past, and where I will be heading. I want to correct some of the shortcomings, I think I had, in the past. I wanted to be sure of what I want in life, particularly in my career. The thought of all these, coupled with fears of failing myself, and other worries for the future may have well been the reason for my mood swings lately. Of course nowadays we don't fight about this petty things anymore, because I learn to shut up and just do it. It's a small thing actually if you think of it, and not worthy of a fight. I guess being married, you learn to swallow your pride more and more. Please don't get me wrong, my husband is a wonderful man. He is a good provider, loving man, who will do anything to make me happy. There are just times when both of us had a bad day, that small remarks result to colossal arguments.
