We are like a glass of wine that can be broken at any time?

I was watching a documentary about the suicide bombers in Bali. Who a couple of years ago murdered 200 or 300 people in two discotheques.
One of the survivors said that in a moment she was talking with her boyfriend and at another he was not there anymore and she said “we are all like a glass of wine that can be broken in a split of a second”.

This, is so true for me. Shouldn’t then we treasure these moments together? We lose our loved ones, yes in that split of a second.
