Let’s stay inside this week. After bitter cold and heavy rains, the borough offers poetry, film, art, dance, sand stories, Muppet music, essential oils, cooking lessons, and wacky performances in climate-controlled venues this week. One event starts within four walls, but then ventures outside. Jan. 18, Open Mic Tribute to Martin Luther King Jr., 6 pm. A special MLK celebration with the poetry of Charles “Smooth” Williams Jr., Harriet White, and anyone else who wishes to join them.
