Alexa, do a 3D scan of my middle finger.
Alexa, alter my finger so that it is 35% larger.
Alexa, now do a 3D scan of my biceps. Alexa, please now add....

I am sorry, I can not do that. Your credit card is already at its limit. I have sent a message to your boss and told him you want to work some extra hours this month. Their Alexa and I agreed on 12 extra hours per week, starting tomorrow: You'll start 2h earlier. I will remind you about your biceps in 2 weeks.

...

Ahem, Alexa... it's ok, cancel those extra hours and let's forget about my biceps. I need to spend some time with my kids.

I am sorry, I cannot cancel extra hours. Your compliance is non negotiable. If you don't show up early tomorrow, I will send your d*** picks to all underage kids in your neighbourhood and I will notify their parents.
You don't want me to do that. Or do you?

Resistance is futile.
