In a scenario where Mary and her father move into the apartment of Rita and her daughters, what reaction would you predict from the girls?

• A. Melissa and Sandra will feel like unwelcome guests.
• B. Mary and her father will be seen as intruders.
• C. They will easily become one big happy family.
• D. Mary and Tyrone will exert their territorial influence.

Answer: (B)

When a new pair moves into an existing family home, children whose routines, space, and relationships are already established tend to interpret the newcomers as outsiders. This scenario tests how boundary and territory feelings affect children during family changes. The girls have their home, rules, and connection with Rita, and bringing Mary and her father into that space rearranges those boundaries. Because territory and belonging feel emotionally salient to adolescents, they’re likely to view Mary and her father as intruders at first, reacting defensively as they negotiate these new boundaries. Over time, with supportive integration and clear plans, the dynamic can soften, but the initial reaction is a protective boundary response.
