My twins are 18 - going to Uni in a few weeks. Following an intensive period of work at school for their A levels - they were temporarily relieved of their chores and then they argued they needed a break and then they just argued with us because they don't want to help out.
Dh and I both work full time and we are feeling the whole - they are treating this like a hotel vibe, we are arguing with them a lot, they promise to do more and then when asked they moan or worse argue - I have withdrawn privileges - last night even went so far as to withdraw dinner - ds said he shouldn't have to do anything because he works, I do too - welcome to adulting.
I feel this is another bloody stage where they want all the privileges of being an adult without the responsibilities.
