Here's what I'm not sure about: If someone who wasn't originally on the guest list talks to you specifically about the wedding, is it against etiquette to still not invite him/her? The last time I was at home for the weekend, David and I ran into one of our classmates from high school. One of our mutual friends reads my blog, and had shown her some of my ideas/projects. She said she loves everything I'm doing and was super sweet about it. The thing is, we hadn't originally planned to invite her because we hadn't really stayed in contact with her since we graduated. This has happened a few other times with people who we weren't planning to invite asking about details (date, location, etc.) or commenting on how excited they are for us. Are we "obligated" to invite them if we talk to them about the wedding? Of course, I'm not saying we should start conversations with people about our wedding if we don't plan on inviting them, but I don't think we should try to make room for people that we aren't as close to solely because we were polite when they asked about our upcoming nuptials.
What are your thoughts? Have you run into this problem? On another note, what percentage of your guest list are you expecting to decline/not attend?
I would definitely recommend using WeddingWire! We're starting to collect addresses to send our STDs and it will definitely help in keeping me organized (read: sane!)
