Wise words, indeed.
We often fail to appreciate people-- perhaps we have occasionally tense relationships with them-- until they are no longer around. My mother (now deceased) used to say "PLEASE send me flowers while I am alive and can enjoy them... they are SUCH a waste for funerals!"
That is true.. we are so consumed with our own stuff that we tend to forget expressing our love to our loved ones, particularly parents.
And I just loved the words your mother used to say to you.. thank you for sharing that. May her soul rest in peace.
