Over the years we’ve holidayed with the same three couples and one singleton, all easy going and flexible. Of course sometimes we go along with something we don’t want to do as others do for us.
One year another couple, liked by all of us at home, asked to join us. It was horrendous, they insisted on seeing everything within a 30 mile radius and sulked if others didn’t fancy it. Only cooked on one night of fourteen and complained about the food prepared by others. The fortnight passed of course, the difficulty was getting away without them for years after, caused a bit of upset.
I certainly wouldn’t spend good money on a holiday with anyone sulky, selfish or controlling. That’s my idea of an incompatible companion.
