What part of "please RSVP either way by August 20th" do you not understand? Especially, since you actually WANT to attend. And how is it my fault that you failed to respond even with the reminder I sent out two days before the cut-off date? It's not like I can add you now; after all, it's a Major League Baseball game which required me to order and purchase tickets by a certain date, hence the RSVP date I posted on the invitation.
The fact that there are quite a few of you is seriously disappointing. Though, it doesnt surprise me since none of you can turn in your timesheets or submit staff reports by the deadline, either.
You all suck, and I'll be sure to text you a picture of me with my beer and hotdog from the outfield just so you know what you're missing!
