Why is the deletion of WeChat one-way?

This design makes many friends feel uncomfortable. Maybe they are used to QQ software. When deleting friends, you will also delete yourself from each other's list. Maybe the other party has deleted you and cut off the relationship with you. You don't know, you are still admiring yourself and secretly love a flower. You didn't understand the truth until one day, when you got up the courage to send her a "hello" message, prompting you to resend your friend's verification. It turns out that you are no longer her friend, and sad tears flow in your heart.

So why does WeChat delete friends in one direction? I summed up the following reasons:

1, WeChat exists to replace SMS. Wechat friends are not called friends, but address books, just like mobile phone address books. Deleting contacts is a one-way deletion. Therefore, when Wechat deletes friends, it just deletes the other party from its address book. Whether the other party deletes it has nothing to do with you, because it is someone else's address book.

2. This may be an imperfect place at the beginning of the development of WeChat, but the function of WeChat has not been perfected until now. But it's also quite good, which is convenient for deleted people to re-initiate chat requests. Unlike QQ, in a rage, they deleted each other and couldn't remember each other's QQ number. It will be difficult to contact later. If you are a lover, you may lose a kind of fate.

3. Compared with QQ, WeChat pays more attention to the protection of personal privacy, such as posting comments in a circle of friends, which can only be seen by friends. Maybe it's my privacy that I delete her, and it's her right to delete her or not. Why should the other party know?

4. After being deleted, I don't know anyway, and it's good to be able to look at her avatar every day. However, some friends reacted, hoping that both lists would disappear after deletion, just like QQ, so as to avoid wishful thinking and wasting expressions.
