I guess lurkers mostly just want to stay lurkers! Well, I did get two entries. Both sets of answers were the same (mostly correct), so the winner is the author of the first comment and that's Heatherly! Let me know what kind of hat you're interested in!
The correct answers are:
0 = number of nieces/nephews I have. I do have a brother, and he is married, but they don't have kids yet.
2 = number of times I've been to Europe. I went all over Ireland on vacation once, and once to London on business.
3 = number of my father's sisters who are named Maria.
5 = number of times I've had pneumonia. Once for every winter I spent living in Canada.
12 = age difference between V. and me.
15 = number of years I've been working full time at my current job. I've actually been working there 17 years, including 2 years part time while I was still in school, but that conflicted with the next answer.
17 = number of first cousins I have.
24 = number of years I've been living pneumonia-free in New York.
31 = number of lipsticks I own.
