If you met an exact clone of yourself in a symmetrical room, you wouldn't be able to have a normal conversation because of your clone thinking exact the same thing, thus wanting to talk at the same moment every time, amirite?

Just because someone's an exact clone of you doesn't mean you'd both be thinking the same thing at the same time. If there's not some debate in your own mind over what's the best way of looking at things or what's the best course of action, you're not really thinking. So if you separated into two exact copies of yourself, I'm sure you could easily get into a heated debate with yourself on a variety of topics.

No because in order for you to think the same thing at the exact same time, you would have to have been through the same experiences, just because you have a clone doesn't mean you are the same in every way, you are only the same physically and have the same disorders.

That's really not how cloning works.

It's called a mirror.

is a twin a clone ???
