An unbelieving smile flits on your eyes when I come to you to take my leave. 

I have done it so often that you think I will soon return. 

To tell you the truth I have the same doubt in my mind. 

For the spring days come again time after time; the full moon takes leave and comes on another visit, the flowers come again and blush upon their branches year after year, and it is likely that I take my leave only to come to you again. 

But keep the illusion awhile; do not send it away with ungentle haste. 

When I say I leave you for all time, accept it as true, and let a mist of tears for one moment deepen the dark rim of your eyes. 

Then smile as archly as you like when I come again.
