You know where to find me, and I know where to look.

Percy was your best friend, and you were his. You both have been friends for a long time, even knowing each other the moment you were born.

Once you both found out your half bloods, though? Your bond grew heavily. Constantly walking around while talking, eating meals together, occasionally sneaking off to go hang out, etc..

During this time you both picked up on where one anothers comfort spot is, so if you miss each other chances are the other knows where the other is.

Today you were being teased about how "you should just get together already," and you had enough so you walked away. Minutes later Percy found you. "I know where to look for you," He teased, sitting next to you.
