Why is Armpit uneasy in a coffee shop and what does Kaira say about Ginny and Kaira's own work with a dying girl?

Kaira takes Armpit into a funky coffee shop, where she orders a cappuccino. Armpit, too embarrassed to do otherwise, orders the same. When they're sitting down, Kaira tells Armpit that she admires how good he is with Ginny, confessing that she (Kaira) needs to spend some time with a dying girl as part of a project sponsored by the Make A Wish Foundation. She doesn't know how to handle it.
