Andover , Choate, Lawrenceville or Hotchkiss?

Hi, Your reply is a great help. Thank you!
We visited all the campus but Andover twice, LOL. We agreed with what you said.
In Lawrenceville, how do students from different background interact with each other? In a high school that I am familiar, Asian kids tend to stick together, as well African American kids, etc… Even I believe Lawrenceville school will encourage the interaction, do you think kids are genuinely enjoying learning different culture and backgrounds? That is vibe we are more looking for, warm with open minds.
