Sixty-Five Million Years After My Death

How long after my death will people forget me. I vaguely remember the bird, the family, and my lover. The name on the tombstone has long been invisible, and I will be a speck of dust. I once loved freedom and peace, but I was a caged bird. Bird! Why are you flying! You have never seen the blue of the sky, Not to mention the dangers in the sky, But why do you yearn for it!
