-"I AM NOT CUTE"
-him always sneaking up behind you and scaring you
-you trying to sneak up on him to scare him but failing every time
-"Spooky Scary Skeletons" being your ringtone for him (you have a demigod-safe cellphone that Leo made. Don't ask how)
-you being shocked when you find out that he actually likes Italian opera
-you both listening to Italian opera together and him translating for you
-you seeing the more sensitive, loving side of him
-him crying more at movies than you
-him coming up behind you and resting his chin on your shoulder
-him being a super corny cheeseball when he's alone with you
-him saying cheesy pick-up lines that you try not to laugh at (Leo always told him to say those. I don't know why he ever accepted his advice...)
-rare but adorable kisses on the cheek from him
-him eating at your table
-you seeing his goofy side when Mrs. O'Leary is around
