Don't feel bad! I did basically the same thing today. I was carrying laundry to the basement (using the outside door like my sign requested ) and Nicki asked to go out. I said, "C'mon, I'll let you out and come get you when I'm done the laundry." Well, I came and finished the laundry, went back in. A while later, I had a headache, but no more Advil. I live across the street from RitaAid so I walked across. While trying to cross the street with my precious Advil in my hands, I see Nicki mosey-ing along eating grass and enjoying the sunshine! I'm a bad doggy mom! I too never noticed her on my heels in the house after I did the laundry... and she is always on my heals!
