Light...

Navigator : Captain!!! Light!!! We are seeing light again!!!

Captain : *Thinking* At last...after wondering in darkness for so long...

Navigator : Shall we change course to the direction???

Captain : Yes...But we need to know what kind of light that is...Will it lead us out to another vast ocean or towards a waterfall?

Navigator : Full speed ahead?

Captain : Nope...Slow n easy mate...
