Hi again, thanks for the replies on this. Not read them all yet (when I left the thread there were about 10 replies, now there's 333!!!).
A few points - DSS was doing an agriculture course at college. Level 2 for a year, then level 3 - all of this was around 2 days a week and half the time he didn't go as he "slept through the alarm". Since the college course he has been doing volunteering here and there so fair play to him for that - but we're talking one day a month or so. He says he's looking for a job but he clearly isn't. His first excuse was that he didn't have a car so couldn't possibly work. We refused to buy him a car but his mum gave in and provided the car. Now his excuse is that he doesn't want to miss out on volunteering as it's the only way he'll get a job doing what he really likes. I can see his point (slightly!) but wouldn't we all like to sit about waiting for the ideal job to come to us and expect everyone around us to pay our way?
He does get money, I'm not sure where from but he's just spent £60 on a new playstation game so he must get money from somewhere.
Anyway, no he never asked to come but DP is assuming he will want to. Ok so I'm being unreasonable to expect him to pay a contribution towards the actual cost of the holiday but I still insist that he should surely bring spending money! not for everyday food and drink but for the alcohol, sweets and toys that he always asks for (surfboard/new sunglasses, waterproof headphones etc).
Last year he asked DH to take him to watch a band. So he took him - he then continuously asked for beer all night. DH at one point said "didn't you bring any money?" and he replied "no sorry, I'm a bit skint at the moment". So DH runs off to the cash machine!!! in my world, if I'm skint, I don't get to go, simple as.
And yes, as I already said I WOULD expect my own kids to contribute and they already take their own spending money.
