Love Harry's beard, and I think William should grow one. I suspect he would look very much like Edward VII and George V.
I don't think Meghan has left home, family, etc., to wander naively into a completely new world where she has trouble finding her feet.
She left home at 18 to go off to a very selective university in a completely different region, joined a very selective sorority there (Kappa Kappa Gamma, aka 'Visa Visa Mastercard'). There is some serious money and privilege in universities like Northwestern and in particular in a sorority like KKG, which is heavily identified with the upper middle class and the very well off. It was very unusual for a young woman of mixed race to be accepted in KKG - sororities tend to be racially segregated. You get into any sorority by fitting in in terms of personality and culture, and by conforming to dress codes and codes of personal appearance, but there is definitely a 'type' for each sorority, and MM clearly fit the KKG mould. So would many young women who went to all-girls high schools in Hollywood or any other UMC area.
She passed the foreign service exam and all the rounds of interviews necessary to work for the State Department and worked in the US Embassy in Buenos Aires for a while before deciding to take her chances acting, and she made it in that field too.
