I have been playing football with my son again and he's asked more questions.
Can a player of the same team foul another of the same team.
I said yes (Hales and Flanagan)
How does the restart occur.
I said free kick to the opposition, from where the incedent happened.
comments welcome.
I may have to stop playing football with him if he keeps this up.

Correct, I think. Remember the Newcastle incident when Barry intervened?

Yes. Those two fuckwits were in the process of knocking some sense into each other and GB stepped in to separate them.

He said something in the way of "Yes, I stepped in. Nobody wants to see that". I thought he could not be more wrong, and plenty of people would pay good money to see Racist Rat Boy and the other dipshit kick the crap out of each other.
