Severus Snape always prided himself on the fact that he had an... iron will if you would call it. He almost never cried. But that does not mean he didn't cry. Oh he has cried. Much more than he would be willing to admit. The thing is though, that the tears he has let slip, all have one thing in common. A certain person, a certain girl, a certain Lily. His Lily.
