Just had an utter blowout with DS (again). He is 18 and lives at home. Works 18 hours per week in a supermarket job in the evenings (3 nights) and pays no rent or expenses - we pay for his phone too. He is doing a summer abroad this summer and then going to University next September.
DH and I both work FT in stressful jobs and have 3 other younger DC (16,14,10). Whilst DS is at home in the day we do leave him some jobs but not many - he has to walk the dogs everyday but often that's it. He would never think to do anything off his own back - for instance if the dishwasher is finished he wouldn't think to unload it, he would just leave his dirty dish on the side. I don't really ask him to do housework as I can't stand the fact that it's generally half a job. I have stopped doing his washing as he couldn't even be bothered to put in his washing basket. I don't clean his room either.
On Saturdays DH and 2 of the DC do the same sport. Often they are at different venues but DH generally coordinates it. DS is very poor at organising himself which will often have a knock on effect. So for instance, he is unreliable at informing us of his fixture which then means DH has to adapt plans or wait around at the last minute.
This morning they are all off playing. DS is playing at a far off venue which requires him to get the train. DH will have to leave an hour early to drop him off in time. We got up early to walk the dog. Get home and DS is still in bed. We're then rushing around trying to get lunches ready, kit etc whilst he just sits there eating his breakfast and watching something on his phone. DH asks him to help. He does nothing but get himself ready. When he comes back down all the jobs are mostly done but he's just stood there listening to music. DH gets angry at him to which he responds loudly and aggressively as if somehow this is unreasonable. It is at this point I lose the plot and I did really shout which is not ideal and I did apologise for that after. I'm just so angry that everything is such hard work. He does not seem to grasp how utterly privileged he is. He is so, so incredibly selfish.
I thought this was a DS thing but my other DC is 16 and is also quite similar. Absolutely no concept of the needs of others.
YANBU - all teens are selfish arses
YABU - your dc are just entitled and selfish
