Never did well on some multiple choice questions as 2 of the options would be applicable, and finding the 51% vs 49% differential turned it into a WAG...
So, would have to say for the first part, a combined A and C - alcohol and the outing of her "closet exhibition" tendencies.
For part two, would be a combo of B and C, slightly embarassed but thrilled, and would love it and laugh it off.
BTW - did find a pic of a girl who looked like my wife when she was younger in almost exactly the described situation, difference being it was outside in the woods... Never could determine if it was her or not.
