I was drinking my first coffee in bed and felt too lazy to get up to go wake up my daughter - who is not a morning person.
I considered taking Banjo over to her room and make a start at teaching her to pull back the doona on cue. But was still feeling too lazy to get up.
So eventually I jokingly asked Banjo "Where's Ella? Where is she? Go get her!" and to my delight, she trotted off wagging her tail and woke Ella up in the usual way: by jumping on top of her and licking her face. I don't think my daughter was very impressed, but it worked amazingly well.
We have a new alarm clock!
