Im trying to remain open minded here, but i feel really disappointed by this. My middle sister has had the invite to my shower for weeks now (late June). She just texted me that she and her husband might book their annual 2-week Caribbean trip and leave 4 days before shower. I reminded her about shower, she felt bad, but then explained:
Ramadan in July (her husband observes this) so they can't go after shower. (It's intense: fasting until sundown, etc.) I get it.

They don't want to wait until August cause apparently he is having a meltdown at work and "needs to get away ASAP"

If they delay it a few days, they will also be away during nephews bday (their son who is going with them) and they want to celebrate his bday here all of us together.

So therefore, they must leave June 18 before Ramadan and nephews bday.

I guess it's bratty to be hurt by this. Other people will be there. It's just... It's my shower and I wish ALL my immediate family would be there. Would u be disappointed but kinda get it (my stance), or would you totally not care?
