Two young granddaughters, Kate and Erin, wrote a letter to their grandmother Jo to wish her a Happy Mother's Day and express how much they love her. They recount memories of her helping their mother and father take care of them as infants, visiting them in Seattle, hosting them in Portland, and accompanying them on a family trip to Mexico. They appreciate her gifts, fashion advice, sweets, and playing with them. Their mother Darby also thanks her mother Jo for all her support over the years, especially recently with the twins.
