My mother tells me always "'could have been' doesn't exist just what is and what isn't"

Why didn't you take Sai to see Torajiro's grave before? Why didn't you let him play more? Why didn't you tell him that you loved him?

Because you thought you had all the time in the world and woke up one day realizing that it had ran out before your eyes. Like sand it disappeared in between your fingers and only regrets are left

These regrets haunt you forever and he's just 14

I'm sad
