To absent friends

This is something you say to people who are not present when you toast. Like friends who have left, friends you used to know but no longer stay in touch with, in short to people who are not there.

Unfortunately I will in future have to say this. Not only to my friend who is leaving the country (only temporary, as I see it) but to somebody who used to be my friend. But no longer is. Sad.

But I guess life goes on. (The show must go on kind of thing).
