Do you?

I sing, I remember
I don't, I still do
I dance, I remember
I don't, I still do
I write, I remember
I don't, I still do
I paint, I remember
I don't, I still do
I walk, I remember
I don't, I still do
I laugh, I remember
I don't, I still do
I talk, I remember
I don't, I still do
I play, I remember
I don't, I still do
I sleep, I remember
I don't, I still do
I look, I remember
I don't, I still do
I think, I remember
I don't, I still do
Do you? even once?
