When you live in a house, your neighbors are separated by...well, another house. When you live in an apartment, your neighbors are separated by what always appears to be paper-thin "walls." If your neighbor is prone to loud music, lovemaking, or dance dance revolution binges at 1am, you have options. Obviously you can have a conversation with them, but depending on the circumstances, it may pay to go to the management or send them more subtle messages. Of course, you could just fill out this complaint form and slip it under their door too. And if you don't have any noisy neighbors...make sure you're not the noisy neighbor.
