Families are funny. They can be sheer heaven or they can be - well, less than heavenly. One thing is for sure, though. The happiest of family members will readily concede that tears are as essential as laughter if we are to survive the dramatic peaks and troughs of close human interaction. This is no less true when love is unconditional and there is a real generosity of spirit in those concerned.  This collection of homely treasures will certainly make us smile, and there is a very good chance that some of them will make us cry.
