He still gets up and walks, with crippled bent legs, as he is very old, a survivor as many rats are. He likes to wear his boxer shorts and shirt, and has one nice suit vest he still wears. He doesn't walk far, but always tries to look up at the stars, slowly, as his neck gives him problems now. He prefers night to day.
He also is made of part love, a bit of stoic pessimism for living so long, and rat like ingenuity. One of kind.
