If we're never apart, we'll only ever have one set of events, albeit from different perspectives, to discuss.
Doesn't that seem boring? Doesn't the pain of being apart pale in comparison to the pain of self-indulgent over-stimulation?
It isn't that I don't love you, so don't even begin to put those self-loathing words in my mouth. It's simply that I value my space and I value that of yours, as well.
