“Why’d you do that?”

I simply hate being asked every time I do something why I did it. I have rights, and I should be able to have the freedom to do something without being questioned why I did it. I don't go questioning everything you do, so don't do it to me. Can I not simply do something just because ? And if I did do it for a certain reason, why do I have to make it clear to you? If you don't know why I did it, then maybe it was because I just didn't want you to know, or you're not involved in it. Just back off.
