damn, 11 is so young. and right before the holidays as well
extend your sincere, deepest condolences for their loss, and ask if there's anything you can do for them (even running an errand so they have food to eat, they prob don't feel much like shopping right now)
find out about the funeral, attend. that's all you can do
I cannot imagine that at this time of grief they give a single shit about your work or the Xian busybodies
