What to pack for a weekend?

Summer is not yet over and, in ten days, the first long weekend of the season is already here. That's why I thought about writing something about how to prepare the perfect suitcase for so few days.

Surely you have a friend, if it doesn't happen to you directly, who drives his car to bursting for a weekend. The worst thing of all is not the hassle of preparing so much and carrying it from one place to another. The really annoying thing is coming back discovering that you haven't used even half of it and that you've also wrinkled or stained clothes that were perfect.

Before continuing, I want to clarify that I am talking about a three-night long weekend. If there are going to be more, then you will have to adapt what you have learned to stretch it a little.
