Who is paying for all these training sessions (coaching fees and for the non-local ones airline fees, hotels)? Dad is an attorney but most attorneys are not huge wage earners. Those that make the big $$ tend to be partners in large law firms that require LOTS of time in the office. So how is dad able to be so involved in her training (including paying all this $$), working to pay the bills, and still able to raise 4 other children alone?
He probably had money from inheritance or property. After all, he did obtain a number of children (was it four?) through surrogacy, which isn't cheap.
