We were unable to attend the wedding of two friends way back in June. They attended our wedding in 2012. We just received our thank you note (for half the gift we sent) and it ended:
We wish you could have joined us on the big day, as we were happy to be a part of yours.
All the best,
Hubs and I feel a bit slighted by this as we were financially unable to attend, as our travel budget was reallocated to our trip to see my family so we could attend a memorial service for my dear great aunt. We let them know in advance we wouldn't be able to come, sent gifts ahead of the ceremony, and wished them well on FB/engaged on social media with the photos, etc. Since that time, they've all but cut off communication.
I'm probably being over sensitive, as I know friends can drift apart over time, but it's just a nice little jab that I wasn't expecting.
