Nah - that's cool.
As long as your lad is ready to reciprocate if ever his sister is in trouble.

That's pretty well exactly what me and my two older sisters are like - you mess with one you mess with all.

I too have this sentiment.
About fifteen-ish years ago this guy I knew, and uually got on with, started hitting the back of my older brother's head. Now, my brother is and was the definition of the 'gentle giant' and could, should he have wished, squashed this insect quicker than you could say "Hulk Smash!" but let the turd get away with it. I presume this i because I knew the guy and also because my brother was three years older than him so may be thought of as a 'bully' for belting him. I on the other hand reacted, shall we say, rather badly. Screaming bloody murder I leapt at the arse-nugget and, had my friend at the time and my brother not grabbed me and sat on me, would have killed him. The only thing that's changed about me since that time is my age.
