Nowadays I think that the meaning of friendship is something that people are losing. With all of the globalization and those stuffs things are changing for bad. People are more individual and doesn´t care about the feelings or just how they are at the moment, how the person is doing at that time. Relationships are more often colder because in the middle of the communication is every time an electronic device in between. Technologies are very important to make business and other things but for relations I find a problem with the communication because we are losing the physical contact with friends, etc.
Since my point of view adolescents are more desinterested about feelings and that is why friendships and relationships are almost all like more superficial. I think that infidelity is more usual than in other times.
For me this problem is very serious because we can´t trust in people and even a friend can disappoint you. Is very sad knowing that all the values are missing and that people are less interested about something that is human like the feelings of other people.
