These people you speak of have souls just like yours. They are on a journey, perhaps unbeknown to them. Our spirits are eternal and given by God therefore we share one Father, one beginning, one ultimate purpose. We are asked to love our neighbour as ourselves, care for them as we would or should care for ourselves and our own kin, because they are ourselves, inside, hidden, just like us.
If you drop a plate you may be annoyed with yourself for a while but then you stop, why? Why don’t you hold a grudge against yourself for years? We are all of the same house, and a divided house cannot stand.
Let it go, peace be with you.
