I struggle this as well in regards to my son. There are some who I know genuinely care. Others...not so much and I know are asking for curiosities sake. To them I simply ask..."why do you ask?" I like all of the suggestions above as well and plan on "borrowing" a few. It's a very self protective place we find ourselves...truly a balancing act. I think you are going to have a great time at this function. Dress yourself to the nines...wear your prettiest smile and they'll all be too dumbstruck to ask anything! Yeah...that's the ticket!!
