Umm...I can think of a time when I was doing a debate (like the educational type.), and I couldn't think of what to say, and was just standing there. :)
I don't think of that as an inappropriate place really. I cry in church a lot. During worship, or if a message really touches or convicts, or if there is huge response to the altar call. That's just me though.
Thanks for your comment :)
In church :(
