To gush or not to gush

I would vote, one of the hardest parts about having a wedding is setting up your guest list. Being on a budget doesn't exactly allow for us to throw the bash of the century, nor is that really what Steve and I want. We want FAMILY and close friends, and people who support us in being the kind of people we want to be; people who lead by example; and people who we have FUN with! Most of our guest list are people we love, people we are happy to invite. But, as always, there are the few obligatory invites, or the ones that you want to include, even though you might not be BFFs. So when it comes to coworkers..... I'm swinging to the "not close enough to invite" side. Part of me wants to pretend like the wedding's not happening when I'm at work, like not talk about the oh so exciting details with them. But I can't help it. It's so lusciously fun to gush over that stuff. BUT, it kind of opens the door for assumptions. For comments like, "You took your engagement pictures already? I didn't see them!" Or " you should have James, from the cafeteria, cook your wedding cake. We can bring it up to Ventura for you" hmmmmm. no thanks? So, the questions is: do I tell them I'm not inviting them? or just let it go like this till it gets closer to the day, and they start to ask where their invitation is? I'm afraid it might be horribly rude, and possibly unnecissary, to tell them "sorry, but we're keeping it small" Maybe I'm reading WAY to much into these comments. Maybe they are just being friendly coworkers, getting exciting with me. I'm gonna lay low for now, maybe cut down on the gushing about it bit, and hope for the best :)
