Football according to Ewan

We were stopped at the lights the other day and there blowing in the distance was the Port Power flag. Ewan pipes up says, "Look a Port Power flag." Meanwhile I am trying to find the Port Power flag that Ewan enthusiastically points out. Finally it is spotted and I then try to rack my brain thinking, how does he know about Port Power? I surmise that he has learnt about football and football teams at child care because we certainly don't discuss football at home. I ask Ewan and he nods with agreement, then proceeds to sing some Port song that also has been taught at child care. I know that there is a friendly rivalry amongst the carers and the football has just finished for the year, so they obviously have discussed the game, the rules and the teams. I found it odd that Ewan knew all about it. At least they are teaching them something at child care.
