Ever had to pause during a conversation

I agree that sometimes silence says more than words. For me, I feel extremely vulnerable when I purposely pause to convey my feelings. Once I was feeling really sad and upset and when I was asked if I was okay I had to stop and think how I truly wanted to answer that question. My friend understood that my silence meant that I was not okay and she helped me get through my rough time. I think that it takes a lot of courage but good things can come from it.
