Somehow it can be right, but totally it is negative for relationship. Take facebook for example. When others can see the parner's status, it will cause misunderstanding between 2 people. Or when the boy is talking to other girl who is his friend, but his girlfriend can not believe that.We know girls'imagination is vast.And when the trust between 2 people are collasped, their love will not last long.
Modern technology has influenced us more than we can imagine.The time we spend with our loved ones are getting shorter and shorter.People have started to value relationships lesser and lesser.
People are more connected than ever , the main reason people think its bad is because they don't know how to use it . For example, many people work away from home now a days and are on very long trips , and programs like FaceTime allow families to communicate. If this was not there people would just have to abandon( couldnt think of a less harsh word at the time ) thier families for a while .
