Many people love to treat their cellphone. Of course I used to treat cellphone a few years ago.
When I went to taking a trip with my husband and my son 3 years ago, I loved to upload my pictures on Kakao story. Then my husband and my son complained me because I concentrated on doing Kakao story without enjoying traveling with my family. Then I was upset because I couldn't notice my behaviors. After then I have used my cellphone when I need to use cellphone as far as possible.
So my cellphone is not my bestfriend but useful friend.^^
