Something you can't go without and a substitute never quite cuts it.

Nothing. I’m not picky, I will eat anything but fast food, but sometimes do if it’s a must. I don’t drink any carbonated beverages by choice, I will use any tool that gets the job done, I will wear any clothes that are clean, use any soap that is available if I’m dirty, and drive anything that gets me to the place I need to go. Yes, I prefer some things over others, most people do, and I’ll drink pop if I want to, I just don’t want to. I’m a simple machine, no off button, and will do anything it takes to get the job done. That’s just me tho, and I don’t complain about much! But when I do, it’s usually a pretty serious beef. And guess what? I get along with about 99% of the people I meet, and the 1% I’m usually courteous to and just go on my way.
