Initially, I thought it was me. I don't think I sound like that when I call the maid but people say kids emulate your behaviour. When we went back to my hometown the other day, I noticed Adam used the same voice when he called out my mom's maid. So it must not be me! I did not talk much with my mom's maid and never raised my voice when I speak to her. Adam spoke politely to all other people except the maid.
What should I do now? Whenever I catch him talking to the maid in that voice of course I will get him to talk nicer but what if I am not around and later it became a habit. I don't want to be the mother who raise a rude son. Sigh~
