almost Japanese, as well as I, is not conscious whether verbs are transitive or intransitive blow by blow, each time speaking in Japanese.
when you speak in English, are you coscious whether transtive or intransitive? I guess you are not coscious probably.
it's a same thing. the estimation figuring out if transitive or not depends on the context.
when you retain the verbs, you need not to separate whether transitive or intransitive. the verb along with object is transitive in the sentense. without object, intransitive. dont take things too seriously.
