Dear Abby: What should I do about the upstairs neighbor’s unruly children?

DEAR ABBY: I recently bought a first-floor condo because I am an older woman with a knee disability. Otherwise, I would have purchased a unit on the second floor of this two-story condo complex. I am only here part time because my husband is not ready for retirement.
