I used to have them on all the time (and it used to annoy my dad a lot, because he said they always distracted him

), but my current TV isn't capable of showing them. I think they helped me understand and remember the show a lot better too. Also, I am a very visual person, and I can understand words a lot better when I can see them. For instance, I love learning languages, but have a hard time understanding something spoken unless I can read a transcription of it. Also I remember words by thinking of what the word looks like, and it's spelling. So I guess it's a similar reason why I used to use subtitles all the time, to help me understand things better.

Oh, I am the same way with learning languages! And my dad also used to get annoyed at the closed-captioning
