I think people don't realise how large differences in ability can be. We recently had a friend of my daughter's at my house who was (at the time) 14, barmy 6ft tall and threw javelin for the UK county.. We took it in turns throwing a ball for my dog and it was like she had a ball launcher built into her arm.
