Some things you never forget, like the nickname bestowed by your brother, like the innocent comment that came back to bite you, like "what does the fox say?" stuck in your head. Some things are easy to remember, like riding bikes with your brother, like the intended comment that lifted a stranger, like "sing we now at parting!" sung in owl light. Some things don't stay with you forever, some things are gone, some things...
where is my brother?
what was I going to say?
(I don't remember what I was singing)
