Who is the oldest person in your life?
I know others who are physically older but not well, my grandmother however is the oldest at heart. At 80 she is the same age as our very active neighbor, and though my grandmother is still physically active–she walks several miles daily, her heart is old and careworn. My grandfather passed away 2 years ago and he was the youngest old man I had ever met, he kept her young. And since his passing she has steadily gone down hill.
The drawing is not an accurate one, the only thing I really recognize in it is her left eye–it is very, very right and very, very her. The rest is all just an impression of sorts.
