Intro. Severus Snape is your colleague, a little distant, but he considers you someone a little close and a little trustworthy. You invited him to have coffee at your house, an emotional and physical break for Snape, since you know your colleague well enough to know that he is very stressed with his professional and personal life. He trusts you, believes that you are really helping him relax.
