My friend's dad accidentally became the most popular person in his apartment building because he didn't understand the group chat. Someone posted, “Does anybody have a ladder?” He replied, “Yes.” Then nothing. The person eventually knocked on his door, borrowed the ladder, and returned it. A few days later, somebody asked if anyone could help carry a sofa upstairs. He replied, “Yes.” He helped. Then someone needed a ride to the hardware store. “Yes.” For about two months, this retired man responded to nearly every request with the same single word. His daughter finally explained that he wasn't obligated to help everybody. He looked offended. “I know that.” “Then why do you keep saying yes?” He shrugged. “People keep needing things I can do.” Last month, the building organized a little birthday party for him in the lobby. He showed up carrying extra folding chairs because he thought somebody might need them.
