The father trembled when he spoke on the stage. Maybe he is introverted, or he didn't overdo it in front of everyone, so he was nervous. However, this is understandable. After all, it is also his first time to give a speech on stage and face the child's wedding for the first time. It's normal to be excited and a little nervous. I think he is very happy at the moment and doesn't know what to say. Even if there are a thousand words, I don't know what to say at the moment. So at the moment, his mood is both happy and excited, and of course a little sad. He is going to be a grandfather, and I am very excited. I am also very happy that the child is finally married. Sadly, he is old and should quit the world of children, and spend less and less time with children in the future. So at this moment, parents' hearts are complicated.
Life is only a few decades, and parents spend only a short period of more than 20 years with their children. Once the children grow up, their parents are old, and the time for meeting and contact is getting less and less. At this moment, I am reluctant to give up, but children also have their own lives to live, and they can only live their own lives. So parents' mood at the moment is complicated.
In a word, when parents attend their children's wedding, their mood is complicated, including happiness, excitement, sadness and many other feelings. It's normal for parents to be a little nervous when they attend their wedding for the first time.
