What are you watching? I guess if you’re in the communal area its frowned upon to change the channel in the middle of a programme if you don’t like whats on!
Talking to a friend about completely random crap (you can pm and talk crap to me if you like)
Reading a book on your phone if it has an e reader
Going on buzzfeed (I’m addicted to it, I like reading funny articles)
Watching funny videos on youtube
Playing games on your phone (I like apple arcade for this but you might not have an iphone)
Thats all I can think of at the moment. I like gaming but I’m guessing you don’t have access to a games console!
