Professor Swenson's encounter with Angela's parents

Swenson meets Angelas mom and stepdad for the first time. He speaks about her in a very good way and they mention to him how much she enjoys and speaks about his class. Swenson thinks Angelas mom looks like her and through what we read we can say she is a little chatty. They talk about the novel and her parents tell Swenson something like this has happened in her previous school. He gets more information about Angela's perspective in the book. But also does not show too much interest to not look suspicious. I feel like Swenson feels guilty and that is why he is so blunt and precise about his words. Also Angela's parents reassure the professor about everything they say and that she is not a part of what happened. They call her a "big chicken" probably because that is what they want to believe. However the encounter is pretty broad and a little weird, the parents are very uninvolved and care more about how she is seen rather than the reality.
