How is Laura deceitful in this play?

Laura is deceitful in this play not for the reason one might normally be deceitful, but rather because she's protecting (or trying not to disappoint) other. Take the business collegte for example...... Laura can't continue there because of her overwhelming shyness, but rather than disappoint her mother, she goes out and keeps the same schedule so she doesn't have to tell her. Her deceits are small one, but none-the-less, she'll use those little white lies when she needs them.

Like her mother and brother, Laura retreats from reality. She’s so far departed that she can’t even see reality anymore. She spends her days going to the zoo, or polishing her glass, or playing records. She has no social interaction, and even her brother, Tom, who clearly cares for her, doesn’t really break into her little world. Yet Laura is rather aware of what is going on. Laura understands Tom’s desire to escape and explains it to her mother. She understands that Amanda relishes her stories of the past and makes that clear to Tom. This perceptiveness, along with her dependence on Tom, her break-ability, and her innocence, all add up to one guilt-inducing memory for the older Tom, the narrator. Laura isn't deceitful in the same way as say Amanda but I think Laura has more going on than she lets on.
