Lesson from a Sunny day

I have to laugh.
One of our outdoor cats, Sunny, is the most lackadaisically fearless cat I've ever seen. Our dog barks and runs at him and he doesn't even begin to flinch. "Eh, no big deal." A car's tire nearly clips his hind leg off and he doesn't even begin to pick up his pace. "Eh, I've been closer. I'll just lay down right here and bask in the sun."
And then there's my favorite. His non-reaction to the gray and white bird that has migrated back to our little patch of acreage.
I know it is the same bird because it behaves the same way it has the last 3 years. Any time Sunny is walking around in the yard north of the house, this bird dive bombs him. From the maple tree it swoops down to just above Sunny's head, over towards the sweet gum tree and back again, chattering at him the entire time. Sunny just keeps walking, oblivious to the bird's rantings and ravings.
I don't know what grievous sin Sunny committed against this bird (well, I have an idea, but I really do not want confirmation), but it certainly remembers Sunny and refuses to forgive him.
I need to take a lesson from my cat. You see, whenever Satan dive bombs me, chattering at me about the sins I've committed, I need to walk on by as nonchalantly as Sunny does. "Oh, yeah, I've been forgiven for that. Move along..." Don't even give The Accuser the time of day off the sundial.
Sunny doesn't let his past ruin his present, and neither should I.
Maybe I'll go bask in The Son.
