I just don't want it

"What is it with you?" I was asked

The dude was walking around like he had something to say, I was doing my best to look busy but finally he just interjected. He was asking if I wanted a certain software application installed on my machine.

It's a nice application. It gives a quality finished product. It looks very similar to something that I use frequently but it's different, different like the difference between a head shot and a mug shot, they are both types of photos, both of the head, usually both are black and white but they really aren't interchangeable.

I said no thanks

He couldn't understand

I tried to explain

where was the photo metaphor when I needed it.
