I know that feeling when plans for outings don't work out; or if all your efforts are undone because people are feeling grouchy that day etc.
But I guess a beach is a beach. I hope that you managed to find a few contented moments, even if it wasn't what you had expected.
I'm normally the grouch :D
It was nice still and hopefully there will be more beach days to come. there is no guarantee with Finnish summers though. Sometimes it is a handful of days and that is it.
