Most people head to the beach or pool to relax and let loose—but
how loose is too loose? Learn which discourteous behaviors—from
blasting your music to letting your kids (or pets) roam
freely—to avoid so you can keep the peace this summer.  Rule #1:
Keep your music down.  Especially at the beach, where there's a
ton of background noise to drown it out, there's no harm in
playing your music at a reasonable volume, says Lizzie Post,
spokeswoman for The Emily Post Institute. But at a beach or pool
that is more low-key, a blaring stereo is not only disruptive to
other visitors, but it can make it difficult for the lifeguard
to hear a call for help, says B.J. Fisher, director of health
and safety at the American Lifeguard Association (ALA). Prevent
someone from having to get up and lug their stuff across the
sand by situating yourself away from crowds and the lifeguard
stand, recommends Post. And choose your music wisely! Certain
artists are just straight-up inappropriate in a family-friendly
environment. Photo: T
