Gibbs- he takes you to his cabin and you guys reminisce about things
Tony- You guys go to the beach and rarely leave the bed
Mcgee- You guys take the whole day off and have lazy day. Not ideal, but you both wouldn't have it any other way
Jimmy- He'd surprise you with a fancy dinner that he attempted to make. The food is burned almost every year but he's getting better
Ziva- She takes you to a fancy hotel and you guys spend time together ;)
Abby- She'd throw you a party for just the two of you and you guys have fun watching movies
If you have any other preference ideas let me know :) I'm going through comments seeing if somebody requested something lol
