William Walls

March 11, 1945 - April 27, 2020

R.I.P. Charles William Walls aka Billy, sweet William, or wild man Bill. To me he was DAD.03-11-45. To 04-27-2020. Yesterday morning I woke thinking hard of my mom. Missing her, only to awaken to my fathers passing.

Some already know I cared for him 2 years while at one point caring for my mom. My dad was a good ole country boy. Simple life. Loved the woods. Connected with nature, and plants. He loved to plant his plants. He would rather be in the yard or woods than in a house.  He is loved by his family. Remembered by his friends. And missed by all that knew him. I love you daddy.
