It is rude and disrespectful. Now..granted..I am probably older than a lot of folks here, but I grew up in a time when there weren't cell phones, and I was a "Johnny-come-lately" with one, anyway. I resisted having one for a long time. As it IS...mine has no apps or anything. It is for specific calls when I am out. As in "where are you". or, "do you want me to get you anything"? I still have a house phone and THAT is where I do my long conversations. Facebook is only done on my PC. Sometimes I put my cell phone down for two days without looking at it. So, when I am out with a person for a day of fun...I am with THAT person. I may check briefly before we go into the restaurant/store or whatever, but the time belongs to them. I am more interested in face time.
