I had these kind of unrealistic expectations that were fueled by romantic comedies, and it has both helped me and hurt me in many ways. It helped me because, in general, they've made me hopeful. I just figure things will eventually work out for me. But nobody is like any Tom Hanks character. Nobody is Hugh Grant. No one is Meg Ryan!
I've always assumed that my parents and my in-laws would live with me when I get older and have children. I just assume it will happen and that it's the right way to do things. It's a deeply Indian custom - that you kind of inherit your parents and your spouse's parents and you take care of them eventually.
