Sometimes it’s hard to know how to help; sometimes it’s hard to know how to ask for help. In recognition of National Suicide Prevention Month, community members settle in for a special screening of “Tales of Harsh Gruder” at Main Street Landing Performing Arts Center in Burlington. The darkly comic short film — backed by a soundtrack featuring legendary local punk bands — follows a recovering addict who receives an unexpected visit from an old friend, setting in motion a night of necessary revelation. The poignant fiction was inspired by the loss of a childhood friend of Burlington-born writer and filmmaker J. Paul Preseault, who is traveling from Chicago to attend.
