My SIL got me thinking about how weird I am the other night at her house. My BIL came home but didn't come in immediately so the dogs were all in a uproar. I normally call Lappy Tubby because that is what they called him when they were fostering him so now he responds better to Tubby than his actual name. After about 2 minutes of "Tubby shush!", I finally just barked "Lappy!". My SIL laughed saying I broke out the full first name he's in trouble now.That's when I realized he didn't have a middle name and proceeded to come home and think one up for him.
