“Enlighten me, what could distract you so much that you could forget your own child, in a car, in the summer.... “
Only about a million different things!
Absolutely no one is exempt from something like this happening. Astrounauts and fighter pilots can make mistakes, get distracted, forget to put the landing gear down. push the wrong button. etc. etc.
Do you really think you are the perfect human being incapable of making these kinds of mistakes? I know the answer. Do you?
No, I am anything but the perfect human. But in all the years of my life, I have never "forgotten" where I put my children, or my animals. Leaving your kids to die in a car is not a "mistake".
Then your priorities are different than mine. My kids are more important than getting my hair done, checking out the latest video or having a blow on a crack pipe. There is nothing more important than your own children, for normal thinking humans.
