I have a pretty big list of co-workers that I would like to invite. If it were a perfect world, I'd be able to afford inviting them all, but I can't. How do I get around the weirdness of having one co-worker find out that they weren't invited, when another was. Do I put a nicely worded note in with their save the date to keep it on the DL? Do I hand them the save the dates in person and tell them? Advice???
