Do you think people with children are happy?

I have no kids. I don't want kids. I am so so happy I get to live my life the way I want. I am single but do have a dog and cat who are my baby's . I feel my life is so great. My brother and friends have kids and they don't seem happy. I don't see them out doing stuff or really anything. Just working and coming home to their kids. I check in on them and the mom's are tired , the dad's are tired. I feel like I'm watching them live like slaves to their children . I don't see them in the best mental state. I am so glad I am still walking through life being able to do what I want. I feel so much happier than they do. The stress they have in their lives is such a contrast to my life. I really do feel my choices were right for me. I do love kids but I'm glad I don't have kids I'm so happy I get to live this way.
