A child's first experience of 信 is with caregivers. When parents regularly keep promises—especially small ones like reading a story or arriving on time—children learn that words are solid. When promises are often broken without explanation, they may learn that language is flexible, more for convenience than commitment. Life will still bring unavoidable changes of plan, but even then, sincere explanation and apology can preserve trust. Parents may need to promise less and practice more, so that 'I will' carries real weight in the home.
