1. Emotional fluctuation: The wedding is an emotional moment, especially for the father. Seeing their children get married may make the father's emotions flood, and he feels that there are thousands of words in his heart, but it is difficult to express them.
2. Nervousness and anxiety: Many people have speech phobia or stage phobia, even in familiar places and in front of close people. Father may be afraid of making mistakes or forgetting what he wants to say at such an important moment.
3. Memories of the past: For the father, he may recall the past at the child's wedding, such as the child's childhood, or the wedding between himself and his spouse. These memories may make him speechless for a while.
4. Worry and reluctance: In some cultures and families, parents may worry that their children will alienate themselves after starting a new life and family. This kind of worry and reluctance may make my father temporarily aphasia at the wedding.
5. Not good at expressing: Some people are not good at expressing their feelings and thoughts in words, even if their hearts are full of emotions.
These are just some possible reasons, and the specific situation may vary from person to person. If you care about your father, you can find a suitable time to communicate with him after the wedding to understand his real thoughts and feelings.
