Girlfriend on her way home from work told me how much she loves me then went to bed mad cuz dint take pup out?

She she basically had a 30 min coversation wit me n her way home from work bein extremely nice and tellin me shes never going anywhere ( as in never leavin my side) Etc. Our cable box had been acting up all day and i even called and had that fixed when she got home. Towards when it was time to go to bed she went to bed aggrivated cuz i didnt take out new puppy out to use it... It was cold outside,we live in the country, and the dog always plays instead of usin it! I told her this mornin it would otherwise be sumthin we wouldnt have to deal with so dont let it effect your mood for the rest of the day... thoughts?
