In the spirit of stupidity and irrelevance alluded to in the title of this thread:
Jeroen, I'm sorry to be the one to break this to you, but, if you bring your girlfriend here, or otherwise get her to accompany you on your trip here, it is far more likely that SHE is the one who ditches YOU - especially if you are already thinking "Should I ditch her now, or later?"
You see, when it comes to relationships, female mice are always one, or two, or three, or four steps ahead - way ahead - I learned that the hard way, with my Minnie Mouse. While we (male mice) are out endlessly working our spocks, and push loops, and off-the-lip aerials, and other stupid sail tricks (including, for some other posters here, how to get planing when there is no wind for sailing, by buying oversized gear - I'm all for it, it's more money for Jeff and Tom), while we're doing all this, they (female mice) spend 99% of their time mastering and practicing and discussing and visualizing the art of how to dump a mate, and keep all his cheese, and find a new better mate in no time at all - preferably before dumping the old one. That leaves them with one percent of their time, which is sufficient for finding a mate and keeping him fed and happy and motivated to go do battle with the Killer Kitty Kat - more than enough!
That's why female mice keep all the cheese, without ever having to hunt for it. And that's why you won't see that many female mice out on the water practicing stupid sail tricks - all the others know that they have something far more important to occupy themselves with. And if, by chance, you do see a female mouse on the water practicing stupid sail tricks, you can be assured that she is just doing it as a novel way to catch the male mouse she has set her sights on. QED.
Of course, this all just strictly applies to mice, and no other species - just like the FDA testing on Saccharin, and artificial sweeteners, and their effect on mouse longevity. Ah, the injustices of animal testing, which we mice are the primary ones to suffer and endure. Do you think any human would endure being force-fed 40 kgs per day of Saccharin? Someday, someday, when this whole climate change thing has run its course, the natural order will be restored, and, in partnership with cucarachas, rodents will once again rule the planet. But that's a different can of worms (yummy-yum yum, just thinking about it).
So, back to the subject at hand, if you don't believe me (after all, I am just a mouse), then just ask anyone to tell you their Maui breakup story, and WHO dumped WHO. Of course, there may be exceptions. But they only serve to prove the rule. QED, redux.
As for you, Giampaolo, whenever I've needed a spare, I've found it in the boot of my car - most production automobiles for mice do come equipped with it. I encourage you to look there first, whenever you are in need of one.
Is this comment stupid and irrelevant enough, or is more needed?
