On the run

Diary of Rocco the PUG.
Mom just told me that I'm getting a cousin...Yeah! Here's a snapshot of him.
My Uncle & Auntie are adopting him on Thursday & we can't wait to meet him. Does anyone have any advice for our very 1st meeting? I ask 'cause my other cousin Annabelle (below) is not too fond of me & I think it's cause I'm a boy & she like to run things. Go figure?
