Incidentally...

....I didn't tell you
when you returned
and I said I'd missed you,
(which, of course, was true),

I didn't tell you (it might
have upset you, or led you to
misunderstand - as sometimes
you do) I didn't say that

actually, while you were away,
those few brief hours, I sat alone
and thought of nothing except
how much I sometimes miss
being alone.
