I think of all those people with phones that easily break because the phone was not made so well. Or because the children are not so tech savvy to make garabage tech work. Like I can. Having been in a highly stressed environment myself, the emotions that drive them to self harm are all too well known for me.
I know this was a typo, but it feels like an unintentional portmanteau of "garbage" and "garage" which seems to fit particularly well. I hope you don't go back to edit this!
