You Know An Episode of a certain anime that you began watching,but stopped in the beginning or middle for some reason..Well I've done it I think around two times..One was a Certain Episode of Highschool of The Dead..I think it was episode six..mainly because I was watching it on my TV..and because of what was happening I didn't anyone else in the house to see that stuff...so I turned it off..and I remember not finishing a certain episode of the anime "Ghost Stories",so yes I've done it.

Most times involuntarily. But there are those ones that I did voluntarily.

It's happened a few times to me. I normally watch anime at night, then I end up falling asleep during and episode xD

Secretly watching anime in class or during school breaks means the risk of stopping an episode regularly. And I stopped D.Gray Man voluntarily because I was kinda bored of it.

Umm well sometimes when i'm watching Naruto or Bleach on the computer i have to stop it but not usually.

I haven't finished the first episode of Naruto or Lucky Star.

Well, there was that time I was watching Fairy Tail late at night but, had to stop the episode because I was half asleep and couldn't watch it. >.>
