I put "her thumb" but was marked wrong. I thought Lurveng was a woman's name. Perhaps she is pointing at the door with some man's disembodied thumb?
Yes, you're right -- I've changed the pronouns to "her".
Awesome. FYI Lurveng is referred to as a "he" in a bunch of other lessons in this skill.
Thank! I'll see whether I can fix those as well.
If I miss some and a sentence with "she/her" gets rejected, please report it as "my translation should be accepted" and/or post in the sentence discussion. Thanks!
