Are you being rude talking on the phone

Here's something i have been thinking about , since i  dropped my cell phone in a cup of coffee and had  to wait for a replacement phone from the Insurance Co I have noticed how ,  firstly we have taken to our phones like babies to a pacifier , i suspect a great number calls made by the general public are dialed  because there is  nothing  better to do  and secondly how rude to be next in line at almost anyplace and hear  intimate details about someone's life being broadcast  out loud for all to hear ! Anyone else feel the same , how about some discretion and good manners .
