Prisons do not allow communication between inmates on parole and those on the inside as prisoners, so any communication would have to be done illegally. Not sure why they have this rule, but as a former prisoner myself, I remember it well. I suspect it might be related to gang activity or organized crime .. making it harder for someone inside to organize heists, terrorist acts or whatever. I'm not sure if exceptions are allowed for this for ex prisoners who are clergy, or in minstry work but I suspect this might be possible. But to answer your question ... the feeling is best described as a bit lonely and longing ... wishing YOU were on the outside and knowing it might be a while in some cases.
