My downstairs neighbor ugh

Quel

So my downstairs neighbor just moved in about 2 weeks ago and I have kids. A 3y/o and a7y/o both girls! My neighbor is a senior citizen with cancer. I been staying in this apartment for 3 years now with no complaints about noise. Every thing my girls do she knocking on my floor ( hitting the broom on the ceiling). Fool falls out the freezer she knocking, one of my kids fall she knocking! It’s driving me crazy as a senior citizen 1 why move to a complex knowing it’s full of women and children? 2 why not move to a high riser where you will get the quietness you need! Then she knocks on my door🤦🏾‍♀️. Cause she want me to tell my girls to sit down and not play tf!!? I’m not telling my kids they can’t play point blank period! The ppl in the rent office should of never moved her under me!
