How can I make an uncle no longer interested in you?

First of all, we need to make it clear that it is very important to respect the feelings and needs of others, so if you don't want to associate with someone, you should tell them frankly, instead of deliberately making them lose interest in you.

If you really think a person is interested in you, but you don't want to establish a relationship with him, there are several possible ways:

1. Express your thoughts directly. If this person has expressed interest in you, you can tell them frankly that you don't want to establish any further relationship. This will avoid letting the other person continue to waste energy pursuing you.

2. Keep your distance. If you are worried that expressing your thoughts with this person will make them feel sad or disappointed, you can keep your distance in other ways. For example, the time to reply to messages has become longer, and the chances of meeting each other have decreased.

3. Talk frankly about your personality characteristics. If you have some special personality characteristics or habits, you can remind each other at an appropriate time and tell them that these characteristics may affect the communication between two people.

Please pay attention to respect the feelings and needs of others at all times. Even if you don't want to establish a relationship with each other, you should express your thoughts in a polite and respectful way.
