I breakfasted alone this morning--and I didn't enjoy _that_.

I said to myself, She's coming to lunch, that's one comfort--I shall enjoy lunch.

That's what I feel, roughly described.

I don't suppose I've been five minutes together without thinking of you, now in one way and now in another, since the day when I first saw you.
When a man comes to my time of life, and has had any experience, he knows what that means.

It means, in plain English, that his heart is set on a woman.
