Learn to Cherish while we still can.

I juz returned frm my fren's granddad's wake. Erm... I'm not good in this. A few questions i myself cant answer...
But i feel that why wuld ppl oni cry n regret oni when a person leave this world? Why not learn to cherish and forgive while we still can? Do we always hv to learn the hard way? Do ppl oni know how to cherish oni when they lose something?

Is heritance tt impt? Does it matter where it goes? y wuld family members wana fight for it?

Will ppl cry for me when i die? (ops... 7th mth.. Sensitive)
