We attended (with grandma and grandpa) a story time at the library and the police came. The librarian read a story, we sang a song and then the story time took a much different turn. The police officer talked about everything on her belt - nightstick (and how to take people out with it, always helpful for 4 yr olds), extra bullets, her gun, handcuffs, and among other items a taser. Did you know that a taser shoots wires out with fish hooks in the end that lodge themselves into your skin and have to be removed from the hospital? I didn't know that either and I don't believe my 4 yr old needed to know that. Luckily, the kids were so excited to see the police car that none of that registered with them (boy did it for the adults).
Blaise wasn't a huge fan of the back seat (good) but loved the front seat (couldn't get him out of it). Who knows maybe a future police officer . . . if so I will tell him not to talk about tasers during story times in order to not scare all the parents.
