Why did we stop talking?

We talk everyday--about insensible stuff like TV shows, movies and crap of the like. Heck, we talk even if we have nothing to talk about. I think we knew during those times that when we're done with one topic, another thing always comes up and that keeps the conversation going. If we can't meet up, we'd usually go on the whole day talking to each other. When we do, we sit across each other in our usual coffee shop and we either talk or silently do our own thing. Awkward silence doesn't occur when we're together. I'm not sure if we're two antisocials hanging together or we're just comfortable with each other's silence. When we partways, we still text like we've never been together five minutes ago. 

We're virtually and literally inseparable.

So how did it happen?

Is it something I said, or did? Or is it something that was always there but we're only realizing now? 

I think it's better this way. But I miss you, I really do.

So talk to me, will you?
