It happened again this year. Foraging through the greeting card aisle looking for just the right Mother's Day cards for the women I adore. I'll admit it, Mother's Day is not a simple holiday for me. It is a one that fills me with love and gratitude and grief.....all rolled up into a 45 minute roller coaster of emotions that leaves me fighting back tears, biting my lip and taking a deep breath when I'm done, in the card aisle no less.
