When is it appropriate to use [sic] in a quotation?

The "sic" expresses that the quotation is exact and true and that any seeming mistakes were there in the original source.

For example, when I say that Sally "wanted a elefant[sic]" I point to the fact that she misspelled it, not I. 

Anne frank was a very difficult person because she would never listen to her moms sometimes her dad even though he was her favorite and in times like that it would make it harder for there parents and other people in the annex to deal with her and since they were just stuck in there the couldn’t do anything but grounding her but even that didn’t work. hope that :
