Why are my HSD discussions being deleted?

They are getting deleted for the same reason that EVERYTHING that Siamese posts gets deleted. Eddie doesn't like you, therefore you MUST be a Cat. Possibly you could have forgot something in the cat box that offended them or you wouldn't settle for Friskies when they ran out of Fancy Feast? Who knows, Eddie is very fickle when it comes to feline things that set him off.

You must have taken a Philosophy course from the Professor.
