I read this post about crying in public today. For those of you who do not feel like clicking on the previous link, I will summarize. It is an article discussing the possible and appropriate responses when you see someone crying in public. The majority of commenters seem to think that offering a tissue or a sympathetic look is the appropriate response. I am fine with that. It makes sense that a person would want to be sympathetic but not intrusive.
If you see me crying in public, do not acknowledge it! It will only make me cry more! Even if I have stopped crying, acknowledging the fact that I cried will (with 98% certainty) make me start crying again! Please treat me like I am not crying. Ignore the tears and sniffles. You can offer me a tissue if you absolutely need to and I don't have any of my own, but then you should pretend I am not crying, perhaps by asking me what my favorite baseball teams are (the Twins, the Royals, and the Braves) or if I have seen Walk the Line (why yes, I have, and I enjoyed it very much).
