With great power... well you know the rest (unless you're the SciFi promo people)

My boss sent me an email, subject: Meeting, that went a little something like this:

Nicole,

Please come and see me tomorrow, Thursday, afternoon after your lunch. Thanks.

Cryptic much? It's about time for our yearly evaluation, so I'm thinking it's that, but seriously, why not just say so?
Basically, I think it's an attempt to make me sweat in some sort of insane boss power trip.
