I've been doing this mom gig thing for 20 years, and I can't tell you how many times I've been on the receiving end of a non-parent's complaint that I'm a failure to society because my child has "gone nuclear" as Matt describes it. Or they complain because my busy kid is busy within inches of their occupied space. If they'd been nicer, I would've been nicer in response, and not attempted to silently goad my kid into annoying them more.
And since this blog post from Matt Walsh sums it up so perfectly, I'm just going to post the link here for you, because I can't do it any justice. Meanwhile, I'm that mom Matt describes in the store, except I'm also telling my nuclear nugget that nobody wants to hear their complaints and howls, so they may as well give it up on making their case for the coveted source of the tantrum. My saying no to them is most definitely not an invitation to convince me otherwise.
