Antagonism at its finest

Why does it seem like people are just out to piss me off today? I just went out to talk to my mother, and at the end of the conversation, I asked her if she had moved over the clothes in the washer into the dryer, because I had washed clothes and forgotten to put them in the dryer. She started giving me an attitude instead of simply telling me that she hadn't. Then she asked my "why I was asking her." It makes more sense to me to spend five seconds asking a question as opposed to walking all the way over to the dryer and checking it. I don't get life.
