Josie made the statement, several times, this evening "I'm homesick". She said this while sitting on our couch, sitting at our table and playing in her room.
I finally asked her what "homesick" meant.
She said "It's when you are sick, at home."
I then explained "No, it's when you are not at home and you wish you were. Like, when we went on our trip? And you said "I want to go home"? That's homesick."
"Ohhhh! So, when you're sea sick, does that mean you want to go to the beach?"
I couldn't really argue with her logic.
