We are going on holiday in sept with PIL and we have invited sister in law, husband and daughter.
Brother in law is messing us about as to whether they are coming - I think in a hope of not paying a contribution to the cost of the villa. I think he figures that if we book it then if they do come along - well we have already paid anyway and it is not extra cost for them to come (we are going to a bigger place which costs more money because they are possibly coming).
He is an unreasonable person anyway (wouldn't let sister in law and daughter come and visit us last year) and I am annoyed that it will potentially spoil the holiday as I will be very cross to have a freeloader there (who boasts that he is too expensive to be made redundant!)
Had it just been us and PIL's we would split the cost half and half no problem - now we have them creating problems.
