When i was young, i used to write letter to my friends. (which is encouraged by my chinese teachers) Of course, writing letters cannot get response quickly. However, the conversation in letter is more trustful, and we will write only to someone we know. Although the process of conversation is long, it really help build a relationship of trust and solidarity. It is because writing a letter can also give a feeling of seriousness. So, we better write a love letter than send a love message.
Here's a song to share.
This Letter P.S I Still love You
With the influence of online culture, people enjoy communication conveniently. That;s why nowadays we use sms texting. As it is convenient, we sometimes send a lot of meaningless message. I am also the one do so. Sometimes when i feel bored, i will send some symbols, like :), to my friends. i would say this is nowadays' culture, a kind of communication culture. In fact, this cannot help build up relationship between people. But teenagers are willing to send this message all the times, even when they are doing others things.
Here's a funny video.
To conclude, building up a relationship require us to pay effort on it. We have to be trustful in our communication with others. Although the convenient communication tools make us feel that the conversation is less serious, we still need to be serious when we are having conversation with our friends!
