Why do some people always delete all the short messages in their mobile phones?

I like doing it, too. There are two reasons:

1. Messages with funny messages or important information, such as card number and address, will be deleted for fear of being washed away by boring messages.

2, sometimes it's boring, playing mobile phone, reading short messages, and deleting them while watching. At the end of the deletion, I got bored, and the text messages on my mobile phone disappeared. I delete messages when I am bored.

Of course, privacy will definitely be deleted, but there may not be ghosts in my heart.
