Well, damn, woman... you should have warned this was not work safe! *wibbles*
I've often thought about this very thing - what was Severus feeling/thinking when everyone else was able to attend Dumbledore's funeral. How his co-workers went from thinking him strong to being a murderer. How very alone he was, surrounded by his Death Eater "family," and unable to even silently indulge in his grief. His jealousy over Potter being allowed to express his emotions and be -supported- by his friends... broke my heart.
*sniff* You know I hate you in the most loving way possible, right?
