Well it sure sounds like she needed a change of pace. Moving to Ghana sounds extreme, but if she’s so paranoid here and can afford it, why not try it?
I expect she’ll be back in the USA eventually.
However she's a light skinned black and they're usually at the top of the social order. No doubt she'll have enough US currency with her which should soften life for her.
She also just might find that her fellow Ghanaians might not be so welcoming to her.
Our church has a missionary FAMILY in Ghana, going on now 15 years. They visited here last year, and I expressed my concern for their safety over there, as Christians. He promptly replied that their family and friends living there are concerned about OUR safety here with all the killings, fires, assaults, attacks, etc. They love it in Ghana, and would not want raising a family back here in the states. I was surprised about his feelings of being safe back there, but not the perception crime here.
