When approaching and starting a conversation with a midget that you're interested in, it's important to remain respectful and open-minded. Start by introducing yourself and politely inquiring if they would be comfortable talking with you. Keep the conversation light-hearted, ask questions about them, and don't forget to make sure they are enjoying themselves before delving into deeper topics. Remember that everyone deserves respect regardless of their size or appearance, so always keep this in mind when interacting with them.
