'Trip'ing out the window

Trip says all sorts of important things during the reading, but one that stood out to me is on page 80 where he comments, "You would have killed yourself just to have something to do." The entire passage from Trip's time at the Lisbon home reeks of boredom and "bland entertainment" (80). Furthermore it gives me the impression that the girls live in a soul sucking psychiatric hospital padded room. Their mother doesn't let them do anything, from judging the suitability of the TV shows to poking Lux's toes with a knitting needle when they rest on the table. Perhaps it is this lack of freedom and identity that drives the girls to suicide.
