Tut-tut, Severus, it was a bit harsh.
I don't agree that you have got nothing in common. You are both warriors and 'Dumbledore's man'. You had similar childhood. You are both passionate about subject you love. You are both definition of yours House. You both had to sacrifice yourself. And much, much more. And I am pretty sure that you like something in Harry. Maybe the way he smiles at you? Or that he like to cuddle? x)
Brilliant as always, my dear.
Hugs,
