As of last Friday I have blocked some of my friends' emails for a week. The reasons for this are kind of... obscure. Irritation mostly, at someone dicking about with a very tired joke. But still, it seems a bit of an over-reaction. Especially when about 50% of my social life these days is carried out under the harsh glare of Outlook Express.
Maybe there's more motive here. I sometimes have this perverse desire to fuck things up. Piss people off that I care about. Mess up when things are going well.

But maybe it's just late and I'm half-drunk.
