Best Last Line in a Letter

Continuing with my theme so far this year. The last line in a letter I recently received. It is so pointed, ambiguous, definite, AWESOME (in my twisted head)...

"...I remember what was, sometimes wonder what could have been, and am grateful for what is. I'm going to stop wondering about what the future may hold for the two of us."

The last (two) sentences...well, I don't know what to say to that.

It is simple. It is honest. It is unassuming. It is witty.

Whoever wrote me that letter...
Thanks. I'm going to stop wondering too. . .
