Why do even the simplest things have to become such a headache

I got my invites in and have a spreadsheet with all the guests addresses. I send the spreadsheet over for FSIL to do the caligraphy. I get a phone call just now from FH saying 'I thought you said this list was ready? There are names without addresses.' Well obviously, they are at the bottom of the list for a reason. If they don't have a name wouldn't one assume that you wouldn't write out an invite for them yet. There are 120 others that can be addressed right now right????
