father and 2 sons

The dynamics between the the sons and the father, and between the two brothers in the misnamed "Prodigal Son" story in Luke's Gospel has fascinated me for a long time:

this study done with nib pen and sepia ink;
did the young son really want to be reinstated or was he just being manipulative? did the older son secretly resent his life with the old man?

Perhaps the young son was being realistic:" best give me the money now, Dad; othewrise it will all go on yourcare home fees!"
