That is when they start asking questions. 

How come we didn't see it?

Why question it when it is already too late?

Then the love is gone between the parents and they either file for divorce or they try and meet their child in hell because they were suicidal and killed their selves

 There is so many things wrong with our world that the only thing you can do is REMAIN STANDING and DON'T GIVE UP

 And know that there is a light at the end of the tunnel

  Even when you feel like you can't

Open your eyes because the pain is excruciating

That you feel the weight bearing down on you

 And you want someone anyone to hear you

 You don't want them to carry the pain and the weight on their  shoulders too.
