The difference between boys and girls

Or perhaps, the difference between a son and a daughter, is quite clearly illustrated by the following incident:

I was standing up near P one day when he playfully decides to beat my buttocks like a drum in front of Calista. She giggles, and rushes ahead to join in the fun by imitating her father.

This is when I rolled my eyes and commented to P that this is the difference between a boy and a girl. P immediately understood what I meant and remarked that yes, if Christian had witnessed P doing that, P would have been charged at in an instant, head-butted, and/or have blows raining upon him.

Ah..indeed, sons are always so protective towards their mums.
