Hi Lisa,
I think your kids are older than our's, but we will be bringing Laran (4, then). And our oldest daughter Caitlyn (CaydennsMommy), will be bringing Caydenn (3, then). As I recall, you have a son around 12 and the daughter is around 7, so they probably won't spend much time together, but who knows?
I told my DW that you recently finished a Masters Degree. Congratulations! I just finished a Masters this summer. I figured she would be interested, because she is all for women bettering themselves. I think she feels like women have always gotten shorted (glass ceiling, etc.). She "hires" women whenever she can (pediatritian, dentist, doctor, wedding preacher, etc.) plus she works for women's and children's causes. What is your degree in?
