Anyone who’s had any experience with farm animals can tell you that the concrete lawn-ornament-style figures that constitute your average nativity scene can’t hope to capture the essence of a fully operational manger. Hence the Aldersgate United Methodist Church’s Live Nativity Scene, wherein a sheep, donkey, and calf (and also, presumably, people) will attempt a more naturalistic interpretation of you-know-who’s humble origins. The nativity will be on view from 6-8 p.m. at the Aldersgate United Methodist Church, Collingwood & Fort Hunt Rd., Alexandria. FREE. (703) 765-6555. (NA)
