If Inter-racial, Inter-caste, Inter-religion, or whatever inter spells complication for you, then i suppose it is wise not to get too involved, or else life just becomes inter-confusing and difficult. Sometimes, it is not always possible to say NO and you do end up getting attached to someone that may be hard for your family to accept. I suppose, in such circumstances it is important to lay your priorities to your family and let them live your life the way you chose. An adult, should have the freedom to make such important decisions for themselves, and if anything goes wrong in the path then they have no one but themselves to blame. A parent, should always advise a child, but never take away their independence and their right to taking a decision.
