To party or not to party?

Self,

Last week, I was working at our satelite office. It's the location of the "Crack Epidemic" and I work mostly alone accept for the administrative assistant (nick-named Septage Queen - SQ) on duty. I've mentioned that I suggested that she start a blog just to develop the discipline of writing regularly. (I do not know if she has as of yet.)
Anyway one day while we were working she asked me for my address. She explained that her mom is throwing her a birthday party later this month and all SQ has to do is provide the address labels to go on the invitations and she wanted my address to go on a label. Now SQ has said she wasn't inviting everybody from work. In fact she was only inviting 2 of the 7 guys in my section that takes turns working at that facility with her....and I am one of the two invited.

She says she's not all that excited about it. She's worried that her mom's party planning/organizing skills aren't that good, but has been forbidden to lift a finger to do any preparations except the guest list. I think she said it's her 44th or 45th birthday, so as far as she is concerned it's not a monumental birthday to celebrate.

All that to say I'm not sure I want to go...or if I should? She knows I'm gay, but that still isn't common knowledge with the other folks in our department. Quiet as it is kept, I always feel awkard in social settings like that when I don't really know anyone there. I considered taking someone with me, and I have an idea who I'll take if she's free.

I don't know what to do, but fortunately the invitation hasn't arrived yet, so I got time....I may even get dropped from the list all together due to seating capacity limits! lol

Look forward to some feedback.

Sincerely,
Pharaoh
