A couple nights ago, FI and I were getting the last of our guests' addresses from his mom. His grandma had said she wanted us to invite a few extended relatives from her side of the family, we said ok. The next day, it occurred to me that his cousin (the one who so kindly set his date the same as ours) may be inviting these same relatives too. That would make us look horrible especially since they sent their STDs back in April (yup, 13 months in advance).
So FI called his mom last night to ask if she knew his cousin invited these relatives too, she said yes. They're having a bigger, more lavish wedding than we are- so I wasn't surprised. Unfortunately, his grandma's started to really lose it cognitively, so we'll have to explain to her again what's going on and why we can't invite these people. We'd be putting ourselves and these relatives in a really bad spot.
