The umbrella, when it rains - Eren. Armin has wanted to, but it always ends up with Eren bending down and teasing him, no matter how high the blonde raises it up. So, he has learned to let Eren hold it, and it gives him an excuse to stay right by his side, so he can at least hold onto the handle as well.The popcorn at the cinema - Armin. He loves that shit, and he lets Eren hold onto the candy, and their drink, typically a slushie mix of the two flavors in the snack center, will be at their arm rest in between them.The baby, when it cries - Eren more than Armin, but fairly equal. Armin is normally the one to get whatever thing they need, because he is better at reading that then Eren, and he is better organized and knows where everything is. The ice cream cone, when they share - Eren, and he loves to snatch it and get some against his pudgy nose, to which Armin ends up rubbing against his. It’s a ritual for them to do that before they actually start eating it, because they lick it off the other’s nose to see if it tastes good or not.The remote, when they sit down to watch a movie - Armin, because he always snatches it up first, because if Eren ever gets it, he knows there is no hope he will ever get it again for the rest of the day/night. He is a little shit like that.The basket, when they go shopping - Armin. It makes him feel glad, and he’s always the one reading from the list. Eren is the one who reached up and grabs everything and places it in, and is always the one to be like a kid and sneak in an extra snack like Armin won’t notice, but he does.The door, on dates - Eren, because he always gets there first, but also does it because he loves doing sweet little courteous things like that. Armin always opens the car door for him though, before he can make it over, so he makes up for it in that way.The other’s hand, most often - It’s equal man, a subconscious thing the two of them do. Not one does it more than the other, because they both always do it at the same time. They don’t even know they’re doing it anymore, like, 85% of the time.Their breath, upon seeing the other on their wedding day - Eren, because he can’t believe that Armin looks so handsome and beautiful at the same time. Armin just smiles with tears slowly falling down his face. He may or may not be wearing a dress and veil as well.The camera, when they take pictures together - Armin, because he loves taking selfies man. He is the selfie king, and loves to edit the photos to make them silly, or ‘photoshop worthy’ with the free apps he downloaded for photo editing.
