Whenever Percy stopped by to see her, she was so lost in thought that the conversation went something like this:
Percy: "Hey, how's it going?"
Annabeth: "Uh, no thanks."
Percy: "Okay...have you eaten anything today?"
Annabeth: "I think Leo is on duty. Ask him."
Percy: "So, my hair is on fire."
Annabeth: "Okay. In a while."
