"Shut up" ... so "let me go"

Tonight, when some enjoy the "Music party" in France or just the saturday night, other like me, are babysitting.
Okay, i know, there is no "Music Party" in England, so that's not a problem to babysit ^^
The problem is coming when your host say to you "shut up" ...

Yes, he did it. Yes, James said to me "shut up". Well, the real sentence was "Shut up and bath them"   :S
In fact, it was bath time and I was preparing the bath for the boys. Rocco was next to me and playing with toys, when he said "shut up".
He is 4, he is just trying to use the "bad words" and everything. It's "normal". So me, because I think he must learn, I said to him "Don't say shut up ..." like a mother ^^
Hum, the thing is, "Daddy" was just behind us... And for him, Rocco has never said "shut up" ... that's sure daddy, you are "STAND UP" of course ... Seriously Stupid !
But as I am stupid too ^^ and sure of me, I contradicted him. That's why he said to me "shut up" ... hum hum is it a reason ?
It's the first time I was so afraid by James. Normally, I try to be not on his way. This man is like a monster ... as big as large. And he is really tall, so you can imagine the picture !
Well, not like "David & Goliath" ... not YET mouhahahaha xD

Briefly, I was et I am even now, very very shocked. I saw in his eyes a storm of wickedness...
And it was impossible for me to don't cry... even in front the children. I couldn't control my tears.
What am I ?
I know already I'm just an Aupair... just a stranger, just a Cinderella who must obey. You know, this feeling, when you feel you are not interesting. Just someone, here or there what's the difference ???

And now, it's soon midnight, they are not come back at home. And because I have not the right to sleep, I must wait for them.
I have really enough of people who think all the time and only about them. I'm full.

Good, now I need holidays and a therapy ^^
