I fully vouch for the authenticity of this.

I only wish I'd been able to find a taker, but I'd already forced my friends to scrape their pennies together and purchase tickets. Except those who a) have the valid excuse of having mandatory classes and b) those who are busy studying for extremely heinous finals.
I suspect you won't have too much of a problem finding a taker for the ticket. As for the absence, you'll be missed, but this is by no means abandonment - not when you'll be there Friday! No cause for guilt, if a bit of sadness...
best wishes,
