How do I get roped into these things

This has been my project for the last 2 weeks (minus the weekend). Tiffany, one of Kevin's classmates needed a dog sitter while she did clinicals in Ahoskie (I don't know where it is either) So me, the one who can't say no, is again offering her services. This is Cody my shadow, he follows me everywhere. It is very cute but when I am sitting on the couch or my bed and he jumps on me it is not so cute. And like with babysitting, been there done that, no I don't want another dog. At least not a 120 pounder.
