I don't know. In my experience, not regularly showing others much emotion usually leads them to over-react when I finally do, especially if it's a strong display. I'll even go so far as to say that a lot of the time, if I know I'm being emotional, I really wish that people would under-react. It makes me feel more comfortable doing it.
That said, in regards to the OP, that would suck to not have your "display" (whatever it was) appreciated to the degree that you wanted.
