My greatest accomplishment

We were discussing something pertaining to our cat Leon this morning and I made Mary laugh. When I can do that, I consider it really my greatest accomplishment. We have recently gotten to the point where we have been together half of my life and almost half of hers, so she has been exposed relentlessly to my "humor," my timing, my jokes, all of it. So getting a laugh out of her when we are not around other people and she is just pretending that I am witty is not chopped liver.
