whats esthers perception of the relationship between doreen and lenny?

Lenny Shepherd is a disc jockey whom Doreen begins dating while in New York. Esther goes out with Doreen and Lenny, but is forced to leave them alone when they become intimate back at Lenny's apartment. Esther sees this relationship as both improper and tempting in a forbidden sort of way. Esther is uncomfortable with both the initial intimacy of the two and then when Lenny brings her back to the hotel drunk. Still Esther wonders what these sort of superficial and sexual liaisons are like. Although she swore to have nothing more to do with Doreen, she takes care of Doreen in her drunken state.
