Rsvps are coming in.

Invitations went out last week and we got our first mailed RSVP back today. We actually put our website on our save the dates. I didnt consider that people would start rsvping from the save the dates but they did on the website. Either way it works.
I was worried about the little postcard from Ann's bargain bridal that we used for the RSVP, but they seem to work.
It's all getting very real, very fast! I also had my first person just want to rsvp in person. And I had my first coworker get upset they weren't invited. I guess another coworker who was invited mentioned to the one that wasnt. She actually tried to shame me a bit about it. She asked why she wasnt invited and mentioned that the other one was. I work in a hospital, so there are a lot of people. This lady I've talked to maybe 3 times ever. I'm pretty straight forward so I just told her that our space was limited and that the only coworkers that were invited are people I'm close to. When she mentioned the one I did invite again, I told her that I've known her for years. Which wasnt the nicest way to handle it but I still thought it was pretty entitled and ballsy of her to try to shame an invite out of me.I'm not sweating it at this point.
How are you guys holding up? Little over 3 months to go for me.
