In "Learning to live with the ringing" (Jan. 22), Tim Smith quotes Baltimore Symphony Orchestra director Marin Alsop as saying, "No one does these things [allows cell phones to ring during performances] intentionally. ... We have to try to be kind and humane." Maestra Alsop is too kind. No one has to bring a cell phone into a concert hall or theater. Leave them home or in the glove compartment.
