How not to be

I used to be...
I had...
I did...
I once...

These are the starts of the stories that I told. I never forgot the intimate smells, visions and textures. Those are the details that make a story wonderful, yours. The problem is that I sometime (more often than not) really never was where I said I was, doing what I said I was doing, with who I said that I was doing, what I wasn't doing, with.
You follow?

Well, that seems to have to change. I can't be two. I can only be one.
