I can relate to that idea of getting warm when frustration builds and I’m guessing lots of other people can as well. Mindfulness and equanimity messaging is everywhere. It’s clear we need strategies to help us deal with situations that bring anxiety like being stuck in traffic or dealing with an obstinate co-worker.
Just because kids can’t drive or have to deal with bosses doesn’t mean they’re immune to frustration (as any parent on the planet will attest). Their problems may seem small to us but they are just as relevant to their day-to-day living. While I might point out that putting on one’s mitts AFTER one does up one’s jacket zipper would be a useful way to avoid a repeated frustration, that observation, in my household, would only serve to further ratchet up the heat.
