In today's digital world, messaging apps like Zalo and Messenger are essential for staying connected. However, a small feature, the 'seen' notification—known as 'Đã xem' in Vietnam—can create big problems. When you send a message and see that your friend has read it but not replied, it can make you feel ignored. This simple notification has changed the unwritten rules of digital friendship and communication for teenagers everywhere.

The main issue is the pressure to respond instantly. Seeing that 'Đã xem' without a quick reply can lead to digital anxiety, where the sender worries they might have said something wrong. This can cause serious misunderstandings between friends. The sender might think their friend is upset, while the receiver might simply be busy, unable to type a full response at that moment, or just needs time to think.

It's important to remember that people have different texting styles. Some are 'Immediate Responders' who type back as soon as they read a message. Others are 'Thoughtful Pausers' who prefer to wait and craft a proper reply later. We should not assume that a slow reply means someone is angry or ignoring us. Understanding these differences is key to avoiding unnecessary arguments and protecting our friendships.

So, what's the best approach? The solution isn't to get angry or worried. Instead, it's about communication and patience. Talk to your friends about your texting habits and expectations. A strong friendship is built on trust and understanding, not on the speed of a text message reply. Being patient and giving your friends the benefit of the doubt is the new rule.
