Sure, there are attention whores but the existence of an outlier of people doesn't seem to me to be a very good reason to shame most people for something that our bodies are designed to do.
The parking ticket thing reminds me of a teenager I worked with once who got a speeding ticket. He started getting really choked up about it. To your point, was it really a big deal? So he got a speeding ticket. He should put his big-boy pants on, pay it and move on, right? Except, what we found out later was that he was crying because he knew what his abusive father was going to do when he got home.
So yeah, sometimes they are on the same level. Context matters.
