I highly doubt the decision to cancel was taken lightly....I was one of the people rolling my eyes, thinking everyone was over-reacting, but I'm now thinking this thing is worse than initially thought, and that some high up people know a lot more than the public is being told.
Also, I just sent my husband to Costco to stock up on stuff "just in case", NOT to hoard, but just to have the essentials before everyone else buys up everything.
I don't like being that way, but I don't want to be that person left without a square of TP while on the throne.
