I am kindof confused now.
I usually state my words clearly in command tone, but I say please, because as stillsmallvoice said, its about being polite. It feels peaceful..
I have been experimenting at just stating what I want today.. And DH asked me why I was so snippy.
I said it with the same tone, just left off the please, and now I sound snippy?
I am not sure how I feel about this.
