I have only cried 5 or 6 times over the years. The first time she got up and handed me the box of tissues. Other than that, we just continue with and a grab a tissue if need be. However, when I do cry it is very short lived and only a few tears.

I work in a group therapy program we strongly discourage clients from giving other clients tissues and our therapists do the same. The reason is that it often can change the course of the discussion and "ruin the moment"
