Calling all poets. Our poetry contest has returned. This year's topic is relationships. We are looking for poems that best convey relationships to children, mothers, fathers, significant others or pets. All entries must be typed, and two versions — one with your name, age and contact information and one free of any identifying marks — must be submitted. The deadline for entries is April 15. The winners will be published in the paper on May 4 and will also be invited to read their work at a Frost Foundation "Super Poetry Hoot" at the main branch of the Lawrence Public Library, 51 Lawrence St. Mail entries to Poetry Contest, c/o The Eagle-Tribune, 100 Turnpike St., North Andover, MA 01845. For more on the contest, call 978-946-2188.
