Thanks for sharing this personal story with us Christine.  It really is true that sometimes just listening can be all a friend needs.  Though let's face it, a cup of tea never hurts.

My Grandmother lived with us for 17 years while I was growing up.  And though not an extremely active woman, she was someone I loved dearly and cherished our special times.  I told her all about my day at school and as I got older I would help set her hair and paint her nails.  As time went on, it did grow difficult as I was impatient, as your friend's son, to her growing old and not being able to listen to my stories.  I miss her alot - she was a really great lady.

Two cents Alert:  Maybe your friend Janet could include her son in some of the care for his grandmother.  Certainly not any of the personal care.  But what about reading with her or taking her for a walk.  Something that might help him feel involved and connected to his dear grandparent.  Just a thought.

All the best, sue
