I have to say I am disappointed in the way Sister's behavior from yesterday has been handled.
My bosses did make her apologize. Unfortunately it was explained to her that she is not allowed to speak to people that way because it makes them feel bad. It's not nice to hurt people's feelings, so she has to remember that. And the apology had to be coddled and coaxed out of her while she fussed and cried and whined.
Um, it was blatantly disrespectful. It was unacceptable behavior, and there should be a clear (unpleasant) consequence for future occurences. It was suggested that next time I should send her to her room. Right. Her room. Which she loves, and it is full of toys. THAT would be a hardship for her.
So now she is under the impression that she holds the power to make other people feel bad, and all she has to do is say the meanest, rudest, most horrible thing she can come up with. I am thinking that will ENCOURAGE the behavior, not stop it!
