Back then, in the quaint time of '06, me and my two siblings had issues with playing the computer too much. My parents decided this wasn't healthy for us. Ever since then there's been a "computer curfew".
On Monday through Thursday, it's 9:00 AM to 11:00 AM. Then after lunch we get an hour of computer time, and then we can play on the computer all night after dinner.
On Friday we have no time limit on our computer after lunch is finished.
On Weekends, there is no time limit at all, but we have to play outside (unless the weather is bad) for two hours.
I really don't see any of it unfair, though.
