So last night apparently in our tipsy and extremely tired state, my wife and I were bamboozled by our old lady Olivia into not making her go upstairs for bed. Which is understandable, joints creaky etc, but what happened was basically she just refused to move when we did the bedtime upstairs call and Birdie miscounted dogs and we both crashed hard, and woke up with no Olive and no idea where she'd gone, which was concerning since the bedroom door was CLOSED ALL NIGHT.
She was found downstairs, on the couch, very pleased with herself and only having gotten into one box of crackers rather than eating all trash in the house like her big sister did.
