japanese-english subs

i don't know much japanese, but sometimes i pick up a few words here and there if i hear/see them a lot in the animes.

because of that, sometimes i find the subs distracting. i wish i could have a way to "turn off" parts of the subs - only the ones i know, so i can focus on the anime more.

is anyone else like that? does anyone else feel the same way?
