fruitsalad, glad to be of help, hope things work out for the best.
If your son has any problems tell him to talk to the Chaplin, they DO NOT just help with religious matters , they are the best at sorting out problems of all kinds. They have a very special place in a jail as they are neither 'screws' or inmates so they see both sides of a problem , they want to help anyone and never expect or ask any commitment to the 'church' or religion in return.
