My parents still take my internet (The Router) @ 9 Pm on schooldays and 11 PM on weekends.
They don't do it to annoy me, even though that's how I feel when they do. They do it because they care and if they didn't do it I would probably stay up until 1 or 2 and would be too tired to do schoolwork or anything else.
My parents are also pretty old (50+) so if they ask me what I'm doing I won't get mad usually. Unless they don't understand what I mean the first 2-3 times I tell them.
