Just want to rant really. I want to ring them and tell them they're rubbish, but I won't!
(and have namechanged as if my cousin reads this then it totally outs and she can tell them I'm mad 
Some background - I have a tiny family; me, my mum, my aunt, uncle and cousin. My dad died years ago. When I was growing up we hardly saw my aunt and uncle due to bad relations between my aunt and my dad (her DB) but my parents split up and we started to see much more of them, having xmas dinner together etc.
They live in my home town which is over 200miles from where I live now, and my mum moved a few years ago and now lives near me, not them.
My mum really likes my DA and DU, and lets them know what is happening with me and my family, and always remembers her DN's bday etc. She insisted we go to my cousins wedding as she is her only niece. I didn't want to go partly due to the distance (DS1 was only 10mo) but also because my cousin texted me on the morning of my wedding to let me know she couldn't come as she was busy (even though she'd have known at least 24hrs before as thats when they would have left home, but probably decided weeks before not to come. But, my mum couldn;t go without us (ill health) so we went.
So. When I had DS2 my mum called and gave my aunt the news. My aunt said they wanted to come to the christening when we had it and to make sure we let them know. She said of course we would (they came to DS1's christening. My DU is quite religious so is very pleased we are going down the baptism route).
A few months later DA calls my mum to tell her my cousin is pg. During the chat my mum said the christening hadn't been organised yet but was likely to be when the weather was warmer. DA said lovely, they still wanted to come, so could we make sure it wasn't in May, as DU was away, and not too close to my cousins dues date.
It was a bit tricky to find a date that fitted in with them and with the godfather who was booked up most weekends, but we managed it and let them know. The date was fine, they said, they'd book a hotel.
Since then we've found out that pretty much all of DH's extended family can't come due to (pre-arranged) plans, but they are all very apologetic. Also some good friends also aren't able to come. But, we know that it's hard to suit everyone.
Fast-forward to today, and my mum got a letter from my aunt with a general family update and an apology. They can no longer make the Christening as they've booked a long weekend away. My mum is furious!!!!!!!
As my DM has said, they are fit, healthy and retired, they could go away anytime. And as DH has said, we picked the date pretty much to suit them.
I really want to call them and tell them that we arranged it around them and going on holiday is a crap reason to pull out. But I won't, I'll just fume at home.
And relax!!!
