What's up With Boys?

What is it with men and weapons? I remember my mom complaining about my little brothers. They were never allowed to have fake weapon toys when they were younger, so they spent the majority of their childhood fashioning guns, swords, sling-shots, Star Trek phasers (sorry Tim, but it's true), etc. out of any raw material they could find. I even remember them biting their grilled cheese sandwiches into gun shapes and shooting each other.

I have always been a "make love, not war" kind of gal myself and have tried to instill this pacifistic ideology in my children. So can someone please explain to me why Tyler chewed his pop tart into a gun today and started making those"pow, pow" sounds that only boys can do? Why, instead of lisping, "I love you Mommy," is my (formerly sweet) son suddenly propelling any object he can heft at me, and slicing me with sword sticks? It's like some macho, blood-thirsty alien has invaded his docile toddler body. My neighbor just laughs and tells me that boys are born this way. However, I am just not sure I am ready to surrender my winsome Ty to the dark side yet.
