When going on a trip, you need to worry about the safety of things and documents in advance. Then you will not have to iron and wash your trousers and jackets in a hotel room that have been damaged by neighborhoods or sandwiches.
The science of packing a suitcase is not difficult. Everything must be done according to logic and common sense. In the center of the bag we put things that we don't mind wrinkling: underwear, socks, T-shirts. Among them, you can put fragile items, for example, a bottle of cognac. We lay books and discs around for strength.
The clothes, which it is desirable to keep in a flattened state, are pulled over this structure. We lay out the rest of the solid objects along the walls of the suitcase: notepads, slippers. We remove warm clothes, money and tickets so that they can be easily obtained if necessary.
