"Mechanic work" needed to be done on his bicycle. And she wanted to help.
She pointed to the wheel and he said, "Wheel, Emma! It turns and makes the bike go!"
She pointed to the pedal and he said, "Pedal, Emma! You put your feet on it and make the wheels turn."
"Someday you'll ride a bike like this, too, Emma!"
She moved the pedal and it moved the chain. She grabbed the chain and her hand got dirty. She held up her hand and he wiped it off for her.
And when she was interested in his face, he even showed her his tongue.
Are these moments common between brothers and sisters? Or are they miraculous? Or both?
