Memory is a peculiar thing. It persists in our brains against all odds. It lets us remember all the highs and lows of childhood and every step along the way. This idea is what unifies the story of Irish playwright Brian Friel’s play “Dancing at Lughnasa.” Set in the summer of 1936 in Northern Ireland, the play tells the story of five sisters (Kate, Agnes, Maggie, Rose, and Chris) struggling to make ends meet and find joy in life. Their brother, Jack, has recently returned from missionary work in Uganda and suffers from malaria. The play is narrated by Chris’ son, Michael, as he recalls the events of that summer many years later. The sisters are visited by Michael’s father, Gerry, on several occasions throughout.
