Sounds like you're not going to do more than 30 days. I don't know the nature of the offense, but "stupid mistake" first offenses won't garner a whole lot of jailtime. If you're being truthful, of course. First thing: Jail is NOT prison. The probability of your butthole virginity being stolen from you is quite low. However, chances of your commissary stash being stolen by niggers is quite high. Also, chances of you being blamed by the nigger in the cell next to you for stealing items in HIS commissary stash is also up there. Get some money in your commissary right away, either bring your own (if they allow it) or have a family member deposit money into your account. You will need it. Your biggest enemy is going to be boredom. If you're going to be there for a longer period of time, say a two-year stint (probably the most anyone will do in the county), get a trustee job right away if you can.. depending on the jail rules. If you don't have a trustee job, your daily routine is wake up, shower, chow, spades, tv, chow, euchre, tv, chow, spades, shower, bed. Shower twice a day. Get ahold of some real toiletries and grooming items from commissary ASAP, that free shit they give you in your bed roll just ain't gonna cut it. Stress sweat smells way worse than regular BO, and you'll notice your own stench pretty quickly. Also, buy underwear and socks ASAP. You'll find it hard to get dry with the tiny towel they give you.. you have to use the knife edge of your hand to "squeegee" away the water from your head and body first before using the towel. Funnily enough, I still do this after every shower now.. Keep your head down. Most people in the county just want to do their time and GTFO without additional trouble. There are a few bastards who truly don't give a shit (usually niggers), and will try to start shit with you in order to extend your time. Don't tell anyone how much time you have, especially if you're a "short-timer." That will just make you a target for the nigger bastard who wants your stay there to be as long as his is. Some jails this won't be possible, they keep a white-board with everyone's info on it in the dep's cage or desk or whatever the fuck they have. Food.. it's hit or miss. County jail food ranges from "not so bad" to "torture by meal." You'll know what kind of jail you're at by the first chow-time.. if it's not so bad, it's always not so bad.. if it's torture food, it's always the torture food. We're talking hard beans and a slice of moldy bologna torture. Good luck. Edit (add): Don't throw any food away, people get pretty dang pissed off about this. If you're not going to finish your tray, offer up what remains to those around you. Cellmates.. I've had mostly cool cellmates or bunkmates (jail cell or dormitory setting). If you find yourself bunked up with a meth head covered in scabs or similar disease ridden shithead, you do everything in your power to get the hell away from that. The couple of times this has happened to me, I explained my situation to the dep or CO in charge, and they were cool about getting me moved. In summation, it's not the most pleasant thing in the world. But it's doable. You'll fall into the routine and before you know it, the dep will come by and tell you to pack your shit- your sentence is over. Remember, it isn't prison! If you have any other questions, feel free to PM.
