It all depends on your tone of voice, not always what your saying i.e you can ask a question without asking 'Why?' as in, how come?
I thought I first understood your question but having read your question again I'm beginning to think either I'm going mad or your question is reallyyyy confusing lol
This is my little boys most favourite question at the moment and i always answer it with "becuase it just is!"
I would have to stretch my brain a little bit too far to give you a proper answer funky and im just not prepared to do that at 8.30 on a Monday morning, or any other time to be quite honest! :-) Good luck !!!!
