What does it mean to be habitually blocked by texting?

Don't want others to see, everyone has their own little secrets.

Don't want others to see the phone is nothing more than the following psychology:

First, for the protection of privacy and personal information, I don't want others to know. I don't want others to see my mobile phone.

The second is that I don't want others to see it. For example, a cheating man will never let his wife see his mobile phone after returning home, and will also set a password. In case his wife knows about his adultery.

The third is that some children don't let their parents watch their mobile phones, which is a generation gap.
