I was going to say we're not a joined at the hip couple and my husband goes out pretty often without me but I don't think he would go to the beach and not take the kids, but then I thought it could be an annual thing the husband does with his mates and has never taken the kids, so shouldn't judge!Something isn't right about that family. Its like they're just lodgers or something. No issue with him going out with his friends, my husband went on a football tour when our kids were little, married couples aren't joined at the hip.
Just seems weird though, to do a thing the kids would enjoy and not take the kids!
