A great friend

This big chap is one of my neighbours children. She has two son's and F is the eldest. He has not long turned 12 and started high school.
He is one of the friendliest children that I know. He is very polite and he's fantastic with my wildlings. X says that F is his best friend.
F will come with us on walks, bike rides and just generally hangs out in the cul-de-sac with my kid's. He is amazing with X. He knows how to get him to come back In the house and just generally knows what works well for X and what doesn't. He enjoys coming in for a play too. And he doesn't mind that everyone is younger than him. I wish there were more F's In this world.
