You choose your friendly girls based on shared values, humor, and interests. You did not choose your neighbor. The lottery of real estate often pairs you with someone whose lifestyle, politics, or cleanliness standards clash with yours. Kindness toward the chosen few is easy; kindness toward the random assignee is work.

You have one free Saturday. The neighbor mentions she’s free that day. At the same time, your three closest friends (the chicas amables) propose a last-minute picnic in the park. According to the keyword’s logic, you choose the picnic. Why? Because the neighbor’s presence requires performative politeness—asking about her job, pretending to care about her nephew’s soccer team. The "chicas" allow authenticity.

| Situation | What not to do | Better alternative | |-----------|------------------|--------------------| | Seeing her in the hallway | Pretend not to see her or look at your phone | Smile and say “¡Hola, vecina!” | | Having a party | Let noise go past midnight | Tell her in advance and invite her briefly | | Pet or child makes a mess | Ignore it | Clean it up and apologize if needed | | She complains about something | Argue or slam the door | Listen calmly, say “Lo siento, lo solucionaré” |

With the chicas amables, you can disagree, cancel plans, or share controversial opinions. If the friendship sours, you stop texting. With la vecina, a single argument over parking or noise can turn your hallway into a Cold War zone. Thus, people naturally invest more in relationships where conflict carries no geographic penalty.

Like any social strategy, prioritizing friendly girls over the neighbor has advantages and disadvantages.
