JoJo knows what the word "go" means when I say it and point away from me. I use it when I want him to leave me alone (like when he's trying to get me to play and I'm busy with something). His response to that word is always to howl. It's like an "ow, ow, owwwwww". I can't help myself...I think it's so cute because to me he's communicating with me, saying "but mommmm, I wanna playyyyyyyy!"
