I agree, it's better to laugh at things like this.
When Hemmes Jr. still played, I was amazed how he could lose from complete nobody's, but beat Soderling at the few times he could enter atp qualies and reach the second round. And every time at his matches I got frustrated, but looking back it was funny when I make it a theorie that it was me, because I've never seen him win when I was present.
At the only match that went well, I had to leave after a few games.
For me it's so much easier with Arno now, I think his on court behavior can be hilarious and when he says he's happy playing and lucky to be on the tour, I believe him. There are many many players who dream of being in his place...
Also from talking to him and Bruno at tournaments over the years... I know he looks scary after a loss, but that's only right after. The rest of time when I see him walking around, or watching other matches, he really seems to enjoy himself.
I do believe that plays a big part too, because I had a job which I didn't love at times, but I enjoyed it everyday 'cause my colleagues were so amazing.
And tennis related again, I've seen a few Dutchies retire (and we all know they aren't the high potentials on tour atm
) and come back again within a year. They all say they come back, because they miss it too much, while at the time of retiring they claim they're fed up with all the losing and traveling....
That's big part of how I made up my theory above.
