 Let's say you waste a shower with all your clothes on. You can go through life thinking that is the best way to get clean. And if you never meet anyone brave enough to talk about hygiene, then you'll never know that there is a better way. There's no reason to be afraid of differences. Limiting yourself to certain topics can render yourself unable to talk to friends, co-workers, or even family. To avoid challenging conversations is the same as to keep your mind trapped in a little box. Open your box. It's an American thing.
