Some people think online relationship is the best for them rather than real relationship it's not expensive because you just stay at home and talking to someone that you love or admire and you can communicate well with them also and aside from that you can share knowledge or ideas.
For me I think real relationship is best than online relationship because I could really see the person that I'm talking to and have face to face communication with them and aside from that I could see the real reaction or feelings of the person.
