I hope your niece likes being photographed naked and having her genitals caressed by strangers. And likes getting her scalp massaged and her bare feet rubbed. And likes having the front of her pants pulled out so that the kindly TSO can peek down and see what she's got.

I have a 12 year old nephew that I tried to somewhat prepare for a trip he was thinking about taking, but being shy myself it was kind of hard for me to get to the point. I did manage to let him know that he could possibly expect his pee-pee to be touched by some guy wearing blue gloves. As his uncle I feel it is my duty to at least prepare him a little for a possible traumatic event. Especially since his father is one of those anything for security people.
