I totally do this to my roommate all the time. He gets so mad when i watch RWBY w/o him! Most recently, we started Jessica Jones together, got 2 eps in before I declared it was my bedtime. We meant to sync back up later, but I binged the rest of it the next day w/o him.
My brother does this to me though. Then he gives me commentary on stuff I haven't gotten to yet, currently usually Naruto Shippuden (I'm only almost done with Naruto). He also busts through new releases of Fairy Tail faster than I can blink!
