Oft it is not the person’s behaviour, per se, that causes our anger or irritation, but our view of their behaviour, our thoughts and perceptions around it. Given that our own thoughts and beliefs play such a fundamental role in how we interpret and respond to the behaviour in question, the line between where the anger or irritation comes from starts to blur. Is it really “external” at all?
About the corgi, in Tasha Tudor's own words: "There is no other dog that can compare to a corgi. They're the epitome of beauty. Apollo can't hold a candle to my Owyn. He has royal blood, the same sire as Queen Elizabeth's corgis, that's why I named him Owyn Tudor after my ancestors. Corgis are Welsh in origin and there are two kinds: Cardigans, which are heavy-headed and have tails that go all the way down, and Pembrokes, like mine, that have no tails and are more refined."
