I dont think that list is overly strict at all
1. They have to use their pocket money to buy their own clothes.
Aside from essentials such as uniforms and warm coats and shoes, I'd very much agree. in our house growing up, if you wanted to earn and save up money for fashion items (levis and DM boots in my day, the parents would meet us halfway if they saw we were making a genuine effort and foregoing our little luxuries to put aside money for what we wanted. But if we didnt make the effort, they wouldnt buy it for us. It taught us to be savvy with our money, swap with friends, hunt around for bargains.
2. Strictly no swearing in their house, one of the kids said "damit damit" and the parents got very annoyed apperantly.
Swearing was a big thing in our house. My parents never swore, not even in the company of other adults and didnt tolerate it in their kids. I'd be a bit more lax myself, perhaps allow swearing at a situation, but never at someone, or being disrespectful to others.
3. The parents control what their kids download (thats fair enough, i would do the same)
4. Weeknight TV is banned
We were allowed a set amount of time that we could watch, and we had to all agree on the programmes - anytime outside of the news times was allowed up to bedtime. I think we got a 2 hr allotment. TV never went on in the mornings as we'd never have been organised enough to get to school on time
5. Mobile phones must be handed to the parents every night.
If they are texting half the night, I'd do this too
6. No Social life on weekdays, no going out with friends on weekdays.
Outside of extra curricular activities such as sports or hobbies or a study group, I'd agree. Weekends are plenty for teens to catch up with their friends - after all they see them all day too.
I consider family life and interaction equally important and between homework and mealtimes and early nights for school, there is not much more time parents can catch up with their children and what is going on in their lives.
