When we come to visit, we do not always behave correctly.
There are a number of actions that can make even the most calm owner furious.
Firstly, few hosts will be happy if a guest starts touching their things. At least if it is done without asking, because you can always ask permission to take this or that thing.
Secondly, you shouldn't stay up late, especially if the hosts hint that they have to get up early the next day.
Bad guest manners are also revealed by bringing unauthorized guests. If you are absolutely sure that your +1 will be welcome as a guest, it is better to clarify this fact in advance.
Fourthly, never feed other people's pets, no matter how cutely they look at you. Dogs and cats in someone else's house can be accustomed to a certain type of food.
Fifthly, coming to visit empty-handed is considered disrespectful to the hosts. It is not necessary to spend every last penny, but it is still worth taking a bottle of wine or a treat for tea.
