Vocab Errata

Hi Hope I'm posting this in the right place! I've noticed that there are a few errors in the Supplemental Vocabulary List #1 (well, at least I think they're errors!): 1. "Brother" is listed, but "Sister" is not. 2. "Stepmother" is listed twice. 3. Both "Son" and "Daughter" are listed as "hijo". My understanding was that "hija" was the spanish for daughter? 4. "Stepfather" is listed twice. Just thought I'd mention it. Other than that, great course! Thanks Chris
