...It seems logical to me to work on the costume that's for a con that's eight months away before working on one for a con that's twelve months away, but they're your costumes, not mine.

I don't intend to be - the fact that you blocked and defriended someone who you once considered a friend and then more or less vowed to never speak to again, and now are claiming that you're perfectly fine around isn't in any way anomalous at all?
