Final answer:
The provided text does not specify where Aven eats lunch. Without specific details from the text, one cannot accurately determine where Aven would eat lunch to avoid others.
Step-by-step explanation:
The provided excerpts do not explicitly state where Aven eats lunch to avoid eating in front of people at school. As such, it is not possible to give a definitive answer to the student's question based on the information given. To assist Aven or a character in a similar situation, one might suggest finding a quiet place such as a secluded area of the school library, an empty classroom, or perhaps outdoors in a less-trafficked part of the school grounds, if the aim is to avoid eating in front of others.
