Aww It's easy to get bored if you just stay inside all day.
I have school, which I quite like, although there are lots of bits which are difficult. But if I stayed inside all day and every day, I would get bored. I need some air from time to time. Although if I take a day off school once in a while, in the middle of the week, I really feel the good effect for a week or more. I need lots of alone time, although, probably like you, not ALL the time!
When I was little my parents and I would go on a walk or to a museum or art gallery every weekend. Now, we never do that, except on holiday. I keep asking them if we can go (I don't have any way of getting to National Trust places, and plus, it's a nice environment to spend some time together in) but they won't. My dad is super busy and my mum is quite busy too. Last time I went out with friends was two weeks ago. It will suit me fine if we don't go out for another two or four weeks, but I think there's something planned in half term.
