I think innocence can appear as...
1. A lack of profound knowledge or at least a lack of an impulse to indulge in on taboo ish matters.
I know people say I'm innocent for never having had a drink until this year. I know people say I'm innocent for never having done drugs. I know people say I'm innocent for never having made out or kiss at all. I know people say I'm innocent when I don't know the meaning of some swear words.
2. A child like style.
A child is considered pretty innocent and maybe it's because of their stereotypical lack of knowledge in hardships and taboo ish issues. It is assumed that without knowledge of bad they will do no bad I guess.
I look pretty young. I get mistaken for maybe fifteen or thirteen. I am short. I have childish halloween costumes such as unicorns.
I know my voice sounds pretty childish. I was in a play saying my lines when this girl I barely know interjects to say I sound so innocent and sweet. I worry my voice is annoying because I sound so childish. It's not necessarily cute considering I'm an adult. I know some people say the words I use seem child like.
Such as...
"Okii", "I'm sleepy", ":3", "^.^", "Hiii", "Aborbs", "Cute,"...
A real definition of innocence is more like refraining from committing evil acts or indulging in criminal or even taboo behavior.
