What's up with some people?

A person just texted me on here and he was asking me questions and I answered them all. But he wouldn’t answer simple follow-up questions that were simple to answer but he just avoided answering them so he said other things meaning he avoided the question. I said why didn't you answer the question, he said “question” and I said, “Yes, what is it?” He said “No questions.” so I said, “Ok, now I’m confused.” I wrote that I didn't want to sound like a bitch or other words he could think off but why didn't he answer the question and why did he say “Question” saying he was going to ask a question but later said, “No Questions” which confused me so I said that saying question is a saying people say to ask a person to be answered. Then boom blocked. What's with people like that can't they just simply answer a question then avoiding it completely and then just blocking you? I don't get it.
