Oh gosh, my biggest cringeworthy moments in my short military career involved EXACTLY this:

Confrontation makes me cry. Like literal tears streaming down my face. For no good reason! Which frustrates me and I cry more.

I still do that, too!! I've just gotten in the last few years to where it doesn't happen as easily or often as it used to, and generally not with strangers. I finally had to tell the Husband "if we're disagreeing and I start crying, ignore it!"
