So AS what did your sister end up doing in the end to fill her time?
She reads, bought a new sewing machine that embroiders and has fun with that, she has 3 kids and 5 grandkids who all live within 20 miles, so occasional babysitting, she lunches with other retired ladies, spends time with family and extended family, goes to plays, goes to yoga, fitness classes, shopping, etc. She also has us stay at her house 2 weeks a year, and this time we're also going to New England. She spends a month here, usually every other year.
