Sorry not me! To me 4 hours is not that far away. And I don't know maybe the OP's parents aren't close to their grandchild like my mom is, but I couldn't imagine in this lifetime, my mom or for the fact even my inlaws who we aren't very close to not attending my child's first Holy Communion for a Johnny Mathis concert.
I guess some families are just closer than others.
I think it is a bit rude to imply that those who do not think this is such a huge issue are not very close to their families.
I fully admit I am not Catholic, so maybe I just don't get it. However, my husband was raised Catholic--in a very religious family. All 4 kids had private Catholic educations, his parents met in the church choir and they still attend mass at least twice a week, etc. I asked him about it and he thought it was over the top to expect anyone to change their plans this late in the game if you told them the wrong dates for a communion. I'll have to ask my mother in law her opinion when we call her this week--I can't see her thinking it is worth getting upset about either beyond a "darn it, I sure wish I hadn't screwed up when I told people the date kind of way."
I so agree! This is a big deal it isn't a 2nd grade school program.
Concert tickets can be sold or for heavens sake just not used for something this special in their grandchild's life. It would seriously affect the relationship I had with my parents if they went to a concert instead of my Child's first communion.
And 4 hours really isn't that far, I just drove 4 hours this evening taking my DD to school and back, wouldn't be a blimp on my radar.
I said the drive was reasonable in this instance (it is not reasonable for us to expect my parents or in-laws to fly to another continent for ANY event for our children--but yes a 4 hour drive is within reason for most people).
Anyway, I guess the way that the people in my family would see it is: BECAUSE we love each other so much we would NEVER let any one event have a serious, negative effect on our relationships. Part of how we show love in our family is by not getting hung up an the details of who was where when and who said what to whom, etc. So, for example, when my brother in law did not go to his twin sister's wedding, we all (well almost all--one person had trouble with it, but even she did not let it ruin her relationship with him, just complained a lot about it to the rest of us for a few months) knew it did not in any way mean his sister was not terrible important to him, or that he was against the wedding, or anything else along those lines. We just knew it meant that attending that ceremony was not working for him (in his case it was logistical--it take a lot of time and money to get from France--where he lived, to Hawaii--where the wedding occurred) but that he was very much a presence in her life.
Given the choice between grandparents who attend all the big ticket things (communion, confirmation, graduation, big birthdays--10, 13, 16, etc.) or ones who miss all of those "special days" (when we are, quite honestly, distracted with a million other details) but are involved on a more day to day level--I would take the day to day stuff in a heartbeat.
