For my DS's 4th birthday we invited four families out on a day trip to a theme park near us. All confirmed attendance and they also replied 10 days before the party to confirm allergies/food preferences.
I invited a close friend's three children and she did not turn up on the day, with no message sent at all. Her children go to a different school, but I see her quite regularly as we help run a charity together.
The party started late as we were waiting for her, and as there were only 6 other children attending, it really affected the numbers.
My children kept asking where they were. For me it knocked the shine of the day, as I felt it was quite shitty she did not contact me at all to say she wasn't coming. I felt disappointed. I had to pay for her kids as there was a minimum number I had to pay for. I had also put together quite personalised goodie-bags for her different aged children.
Friends texted her over the following days, but heard nothing back. So then we started to worry that something awful had happened - illness or bad family situation.
It turns out she had lost her phone, with her calendar in. She could have emailed me, or Facebooked me using her husband's phone. However, she said she didn't think the party was this weekend.
She sent a Facebook apology and I messaged back to say that thank God she was OK, and it was just a lost phone - we were worried. Also that I had goodie bags for the kids. I'm the kind of person who usually re-assures people and says "It's OK", but I felt I could not do it. I feel a bit annoyed. I just wrote "It's a shame you weren't there".
AIBU to feel I can't just say "It's OK?" or "Never mind".
I'm sure when I see her I will check she's OK and be fine with her.
