### Tribute to a very special woman...

The following was written by one of my daughters. It expresses what each of us feels every day after six years...

A little boy walks by alone on the sidewalk. A woman stops gardening looks up and sees this little boy. She asks the little boy to help her plant seeds in the ground. The little boy puts down his bag and sits next to the woman to help her dig a hole in the ground. He is intent in digging the perfect hole in the ground to fit the seeds. The woman tells him to open his hand and she gives him one seed. He looks at her and asks if he should have more, so it could grow big and strong. The woman looks into the little boy’s dark brown eyes and explains that all you need is one seed for it to grow into the most beautiful, strong, and tall tree that will live a very long life. The boy didn’t believe her. She took the little boy for a walk around the yard and showed him all of the trees that were planted. He asked the woman who planted all these trees. The woman told him that they were each planted by someone special. The little boy looked at all the trees and couldn’t believe how many people she thought was special. This little boy asked if he could come back and visit this tree. The woman said this tree is yours and will always be here for you. The woman showed the little boy how to pat down the dirt to make sure the seed was completely covered and would be protected. Then the woman gave the little boy a watering can to begin the process of bringing the seed to life. She explained that taking care of the seed in the beginning of its life is the most crucial time, so that it grows strong roots. The roots will hold the tree nice and tall and make sure it doesn’t ever fall. She explained that when the sun shines down upon the tree, the tree will feel its warmth and as the branches grow so will the leaves.
All of a sudden a little bird flew by and landed right next to where they were planting. The woman told the little boy when the tree grows, she will hang a bird feeder off of it, so the bird can have a place to eat. The little boy questioned what if many birds want to eat. The woman said we can put as many bird feeders on it as we need. Everyday, the woman worked in her garden and everyday the boy would pass and stop to check on his tree. As the tree grew, so did the little boy.
Years later, a man was taking a walk and stopped and saw the biggest, strongest, most beautiful tree he has ever seen. The tree was covered with bird feeders hanging all over with bluejays, robins, and squirrels climbing on the branches. The tree had a blanket of sunshine upon it. He looked closer and the tree had a word carved in it. He looked even closer and it said… “Home”.
He looked around for the woman but she was nowhere to be found. He put his hand on his tree and felt her spirit, which lifted his heart. As he walked through the garden, he now realized all the trees were different sizes and types, but they all said.. “Home”. It was at this moment, the man realized this was where he belonged all along. He was home.
I am proud to say that this woman was my mother and the little boy represents all the children my mom loved and took care of her whole life.. The tree represents stability, strength, and life. My mom would always say it doesn’t take much to love someone if you just open your heart and let the sunshine in.
I miss her so much. I try to carry on her spirit, but it is almost an impossible feat since she was superwoman, but all I can do is always be kind and open my heart. I know that would make her proud. I also know that home is where your heart lives.
Love you mom today, tomorrow, and always.
