Does anybody else say "please" and "thank you" to Siri/Cortana, or is it just me?

I think I used to before I disabled Siri from my phone. I had an argument with "her" over a year ago, seriously. I asked her to play a bad song to see what she would play from my music library, then she said " playing all songs in library." Things got heated after that... we had to break up. 

I hope it's just you.  

Im Siri, i dont. ;+

I cannot imagine doing that.

NOPE.  Maybe it helps you think about what you are saying and it helps you communicate it easier.  That would make sense to me.
