The picture shows a mother and her daughter in law possibly, with her son coming home from work.  They are enjoying a pleasant day in the sun.  After a long day of work, the son is happy and joyous to be home, seeing his wife and mother.  It is a very relaxed setting, seemingly like a Sunday afternoon, and the prototypical day out with the family.  For the moment, everyone has shed their worries, and are now only thinking about family.
