Alexa. please

The other day I said something like "Alexa can you please tell me the weather?" and my daughter said "Dad, you know you don't need to say please, right? It's a robot." 

And my daughter is correct. 

Unless, I'm saying please for myself and the way I want to interact with the world. 

Which, if you get down to it, is most things in life. There is a part of how we live that benefits others but, in the end, it might just benefit us the most.
