Try explaining that to a girl who wants to grow up to be an All Black. She might be faster and smarter and run better lines than any of the boys but she'll never be the rugby hero each of them could be.
Steer her away from rugby. Tell her to play netball instead. At least she'll be paid a professional's wage for being the best in her field. It's the premiere women's code in the country. But prepare her early for the fact she'll still earn less than the rugby playing lads.
Tell her she's lucky she's playing sport in this century instead of a few decades back. If she was around pre-1967, the lads wouldn't even have let her run a marathon.
So, things are on the up. Wimbledon has set the standard for equalising male and female sport. Sure, it took the tournament 130 years to finally do it, but in 2007 it agreed to give the female champion the same prize packet as the male champion. Let's keep the momentum going.
Parliament, next time the netball team wants to announce its squad for the World Cup, how about you let them announce it from the Beehive the same way you're letting the All Blacks announce their World Cup squad at the end of this month?
And parents, how about you grab your kids and watch tonight's netball final, the same way you make a night of watching every All Blacks game? That way, we can teach the little ones to enjoy the top sport of each gender equally.
