I didn't particularly like my parents.
And I know lots of people with children who "misbehave" and don't like their parents.
Obviously, there are also some situations where parents and children are happy together, also later in life.
Children are, especially in Thailand, a huge financial burden. I wouldn't want my children going to a cheap school. So, option 1, I would have to work mostly for the children, option 2 send them to a cheap school, or option 3 having no children. I like option 3. If I would earn a lot of money (lets say >10k USD per month) then maybe option 1 would be acceptable.
