Do people really go about their lives asking personal questions that could really upset someone? Yes, it is rude. Many people don’t consider it a personal question, nor do they think it might be hurtful to ask. Similar to the dipshits who say “Hey, you gained weight!”…..like you wouldn’t have noticed yourself. Tell these people “My wife and I like to keep our family planning to ourselves”. If they ask again, repeat that. Then don’t respond on that topic. Even the dense will get the hint.
