Thought of the morning?

I don't often wish people to leave me alone or not join me in going somewhere, but on that odd occasion, when you just want to leave and go somewhere else, how do you tell that other person in a nice way that you want to go alone, to enjoy the time for yourself?

I guess it's kind of selfish in a sense, not wanting to share in the fun, but it's really just wanting a change, so in order for that, you kind of need to leave that person or those persons... I don't know. I'm on the fence about this, I'm silly. :P
