Have you ever kept a vigil?

I’m keeping one now, for my 16 year old cat, Smokie. Smokes. Smokers. I don’t want to leave but…I can’t stay. I have to go to bed. I’ve made up a good bed for her in the bathroom for tonight, where I can close the door so Dakota (our German Shepherd) will stop slimeing her from head to toe trying to help. I thought about making a bed for me in the bathroom next to her…but I really have to go to work in the morning. Smokes is fading fast…
