Visiting
While there are a few things to keep in mind, the manners when going to a friend's house for dinner or other similar occasions are generally similar to those in other nations. A bottle of wine, some chocolates, or another culinary item might make a suitable gift. In their romantic overtones, flowers, especially roses, it may be a bit less secure of an option. If you do decide to present flowers, don't buy chrysanthemums or an even number of stems because such are typically placed on graves.
If you are hosting guests, it is customary to open their gifts right away. Depending on the circumstances, you should decide when to depart after a visit, but try not to linger too late. It could be best to be cautious around 10 o'clock at night.
