Solitary confinement means absolutely no social interaction at all. Also, sometimes, no light, books, or anything to engage your mind -- it's pretty close to torture. The alternative is not just "locked in with another inmate." Inmates can interact with much broader groups at various times of the day, have access to books, hobby items, games, gyms, etc. So now ask yourself -- would you choose solitary confinement over the alternative?
