I don’t think being cringe really exists when it comes to kids. They are developing into who they are/will be.
Adults on the other hand like myself I could say can be, because we are supposed to(according to culture) have figured out who we are, so when we do something out of place it is an attention seeking act that went poorly often times. So when I say a bad joke, I can come across as cringy, or even me trying to explain myself here can come across as cringy. But kids, we need to cut them a lot more slack. We shouldn’t be punching down on adults either, but if we start by supporting those kids finding themselves maybe it’ll grow with time and eventually maybe anyone can say something dumb and not feel like they should shove their head in the sand, but rather feel safe in their own insecurity and be supported by people around them.
Love for those feeling insecure may be the change they needed to not lash out negatively, whether against themselves or others.
