Time.

It's probably the most powerful word that can destroy one internally. It makes us lose a close friend, family, etc etc. Sometimes you wish others spend a little bit more time with you, lets say 1 min or whatsoever. The feeling sucks when you don't spend enough time with your close friends and eventually they drift away and end up in the 'hi bye friend' category. Same goes for your family, have you ever wondered how they felt when don't see you or get to talk to you. and what's worse is when time is running out for them. Life is that fragile, just treasure every min before you know what meant most to you is gone.
