My younger sister is stronger than me, is that normal?

@FreddieUK We were playing pool jousting over the summer and she knocked me into the water with ease.

@Billybob2 Is it as damaging to the male ego these days as it was when I was young? Your generation seems more accepting of girls being stronger than men.

@FreddieUK I don't think so, I was more taken aback that my younger cousin who's a guy is also stronger than me.
