Gryffindors: People who lean back against walls with one shoulder while they talk.
Hufflepuffs: Hugs that linger just a bit because neither of you really want to let go.
Ravenclaws: Someone leaning towards you from their desk to help you with a question/problem.
Slytherin: That ‘accidental’ slip of their gaze from your eyes to your lips as you’re talking.
