The key to understanding others better is by first knowing and understanding your limits and how much you can tolerate from others. Secondly, and this is for those who have disabilities, try searching the disability or disorder before you openly engage in conversation. This may prevent any up front confrontations that end negatively. And last but not least, understanding your significant other. Make sure you know what makes them happy, angry, sad, any and all disorders, and understand why they do the things they do. In doing so, it will give you a better chance of avoiding major problems in the near and distant future.
Here’s a little help to get you started.
