Dear Ferris and Riley,
You're adorable, and I'm happy that you're playing with each other. It's especially cute when Riley dives down with her butt in the air and bites the carpet while she wags her tail so Ferris will chase her.
But I'm trying to finish breaking this story, and every time you crash into my chair or run under the table you kind of disturb my concentration.
Also, running over next to me and panting heavily while you wait for the other to quit whipping the rope around and get back to chasing you is cute and everything, but I'm not "safe" or "base" so you can just as easily do your thing on the other side of the room.
Stop giving me that look. I'm not taking you for a walk until I get more work done, which I can't do for all the reasons I've outlined in this note. I don't care if you roll over on your back and wag your tail while you look at me upside down.
Hey, I think there are some birds on the patio. You should totally go out there and see how fast you can make them fly away.
Signed,
The Guy Who Feeds You
