Everything that 

 happen     once

 can    never  

 happen  agian.

 But  

everything that

 happen   twice

 will   surely  

 happen   a  third  time

- Achemist - 

 Twice  Of  Meeting.

 Twice  Of  True Love.

 Twice  Of  Separation.

 Maybe   We'll   met   again.

Some day.

Some where.

 We'll met agin.
