Hazel had eventually decided that her and Nico needed to catch up on, well, everything.
Annabeth started a history class for them, taught during their downtime on board the Argo II. The two demigods listened intently, relishing every word. Of course, this was all new to them.
"There's such thing as a phone with a touch screen!" Hazel exclaimed in the middle of a lesson "How expensive is that?"
"Uh, usually a few hundred dollars." By now Hazel looked like she was ready to faint
"Who has enough money to buy one of those?"
"Uh, well, the value of money has, um, changed in the last few decades." Annabeth pointed out "Every dollar is worth about sixteen times more than it was when you were younger."
"Oh. Then can I get one of those phone things." Nico asked
Annabeth groaned. Now she'd have to explain how and why phones attracted monsters.
