Erin: Out milk and bread dad.
Sam: I'll get some on my way back from work.
Erin: Can you get me a Mars bar as well. Pls.
Sam: I might be able to :-)
Erin: Does that mean yes?
Sam: It means I might. ;-)
Erin: Dad! You're cruel!
Sam will buy milk, bread and probably a Mars bar for Erin on his way back from work.
