Are we gonna say next hello ?
Laura Pausini in her song titled "it's not goodbye" has mentioned that : "Till the day I let you go, Till we say next hello, it's not goodbye."
For me, I'd prefer to let the rest to Allah SWT whether to give us chance to say that next 'hello' or not because we cannot predict what will happen in the future. We have our plan and Allah SWT as well has His plan for us, and the best planner is Allah SWT, indeed He will do what best for us. Right ?? >_<
It is just a matter of time ^_^
