My son

He's the middle of three boys.  When you think about a middle child, he would be it.  He just turned 20 last month.  He recently went back to jail, this being the third time.  All for being stupid.  He was always the life of the party, all the girls like him.  First time he went to jail, probation violation.  Second time he went to jail, probation violation.  Now, he's been in jail for almost a week.  Bad luck, some would say.  He is really a good kid.  Just has some major bad luck.  More like stupid moments.  When I ask him why he did what he did, it's always "I don't know".  His friends are no help.  They can't wait till he gets out of jail so that they can go celebrate.  I'm at my wit's end with him.  I'd like to put him on a desserted island some where, just so I wouldn't have to worry about him.  I some times wonder if he realizes how much his actions affect not only me but his brothers.
