Leo: Hello grandpa, can you come over and help me do my maths? please
Leo: Grandpa, are you there?
Grandpa: Hello Leo! I didn't notice your message at once. So you need help?
Leo: Dad is busy and mom doesn't know
Grandpa: But you know it's quite late now. By the time I'm at your place it will be midnight. Do you need my help NOW?
Leo: No tomorrow will do
Grandpa: OK, kid. I'll be there when you come back from school tomorrow.
Leo: You are the best!
Leo: Thank you
Grandpa: Sleep tight, kiddo!
Grandpa will help Leo tomorrow afternoon.
