For example-jumping into a pool filled with below 40 degree water on New Years Eve-not that that was recently done or anything; spending the money that you don't have on an overpriced item-in this case a wallet,which now holds no purpose considering the money to be held in the wallet was spent on the wallet itself; taking a random road trip on a whim, letting a friend drive your car for the sake of not having to drive-warning: don't try this, experience shows that it's not the smartest idea. results vary; or even the simple act of leaving your number on a cute strangers car-not that you know what kind of car they drive when attending a school with no secrets.
In consideration of the latter, like I said before, not every "seize the day" moment ends with the results that we hope for. When it comes down to it, I guess it's not really your fault for seizing the day. It is simply his (the strangers) bad for not accepting a "carpe diem" in return.
