Blue Nile restaurant owner Yosef Haile is often seen with a smile, and recently he brought big smiles to a group of young Eritrean refugees due his unexpected generosity. Jamaica Plain resident Lexi Klupchak is the clinical director for the Rediscovery House in Waltham. The home is for boys ages 16 to 21 with complex trauma histories, and most have little to no family, said Klupchak. The long term goal of the home is help get the guys to live independently in the community with meaningful vocations. "Most of our guys are from Boston but we also currently have unaccompanied refugee minors from Eritrea which neighbors Ethiopia and shares the same food," said Klupchak to Jamaica Plain News.
