Out of the mouths of babes

My nine year old niece is the most precocious child I have ever met. She is incredibly clever, and very smart. She says the darndest things. One day as we sat at the dinner table, we being myself, my niece, my sister and her husband, she innocently and inquisitively asks " what are those plastic things boys put on their penises?" She is nine. I desperately prayed for invisibility or at least the ability to sink unnoticed into the floor as my sister calmly answered her question and my brother in law tried not to giggle. I can't believe I'm really about to say this but... back in my day, we did not know about condoms at nine.
