Life is like an arranged marriage. Parents expect gratitude when we have none. Once we are in it, we have to commit to it. Some of us may not have wanted it but, what we want doesn't matter. Now, we can get a divorce but that's a lot of paperwork. Many of us indeed turn out to be genuinely happy at the end of it but that's not the point. What we need is a choice, to stay or to leave. And denying us that through social pressure is just playing dirty.
