I saw a really sweet incident just now . A dad was walking with his 2 year old daughter and probably 7/8 year old son when his daughter fell down and started to bawl . The dad immediately picked his daughter up and the brother picked up the sisters ' toy and kept on trying to dust it clean to give it back to his sister and stop her bawling .

Generate a question about the above context.
What may happen if the boy does not pick up the toy ?
