Thank you for your answers,
I agree with you, to give a present is good manners and we don´t have to give advice if nobody asks them.
I agree in relation to food, you shouldn´t take additional helpings without being invited to by your host.
I think to check private things is always bad manners.
I think it is a bad manner to open someone's fridge and eat something, ( If the person is not a close one), to enter someone's bedroom without permission, to open people's closets. And to check their messages.
I think, the bad manner is coming for a visit to someone's home without any present - at least small and not great one. Also the bad manner is to give advice, if nobody need it))
