Best is to love someone Worst is that someone doesnt love you

best - life worst - death (i mean unnatural, unnecessary deaths, i.e. sickness, murder, war, etc.)

I think the best & the worst thing this world can offer is none other than....we, the PEOPLE. we are the only perfect being who can make great progress here and unwittingly, we too are the one destroying our mother planet.

there are alot of things that u can say it is the ( best or worst ,) any way , i think PEACE is the best thing in the world ( if it available ).
