For the length of this film, it leaves a strong impact on many. Even if you aren't one of the many grieving parents. You grieve for them as it is a horrible & commonplace event (problem) of the present-day century. Thinking of all the families that have been torn apart over this due to their beloved children's or sibling's demise is utterly heart-wrenching to witness (let alone think about).
Rest in peace and stay strong, you gave your kids a great life while they had it.
They shall admire you from above and remain by your side.
And constantly remember that they love you.
