Dear Annie: This letter is in reference to the aunt and uncle who provided generous gifts to their six nephews, only to be forgotten when it came time for those same nephews to thank them.

"The joy they feel as children when receiving a gift is my joy as well, but once they are adults, it is now their turn to be generous to others."

In today's Dear Annie column, Annie Lane shares a letter from a grandmother on appropriate ages for ending present giving to grandkids.
