no more than the phone did in it's day
just imagine, people used to have to go to one another's houses in order to talk...after the invention of the phone, all they had to do was pick up a phone and talk to the person immediately
then, we got answering machines and didn't even have to talk to one another...all you needed to do was leave a message and the other person could get it later
next, pagers and then cell phones...each is just another step along the technology trail
as far as relationships going south, cheaters have always existed and always will...it's just that it is much easier to do so now and is also much easier to catch them doing so now...it was much more difficult to get away with an affair back in the day when you only had one horse and the husband was using it to plow the field while the wife was at home with 14 children!
