Enjoy receiving!
A folk proverb says "Do not leave for tomorrow the things you can do today". It concerns the presents as well. At the very moment, when you receive a gift, it is polite to open it and thank for it. It is normal and nobody, perhaps, imagine another variant of action. Unlike the wedding ceremonies, the gifts are piled on a table and opened only in suitable time. As for the business gifts, it is better to open them later. In fact, who is going to stop the negotiation and open the boxes right in the presence of foreign partners using every precious minute of theirs?
It is not normal to discuss the presents with other guests, even if the things are really special and good for you. It is totally forbidden to speak about non-expensive presents and compare them with very expensive ones. At least I would not like to experience something like this and I believe it would be my last party at this house. If somebody presents a thing you do not want to have and do not like at all, so, it is not a problem in accordance with the polite rules. You are allowed to tell about this, but only eye-to-eye explaining why you think so. Plus I know that there is a "good" developing tradition to re-send the presents. But, it is you to decide what to do with your presents after a party itself.
A hero of an occasion is to find some warm word for every gift. It provides with good mood throughout celebrating and guaranties that these guests would like to come next time as well.
The flowers are to be put into the vases. It is better to prepare some vases beforehand.
Regarding sweets, fruits, alcohol, it is much recommended to put them on a holiday table. An exception is very expensive drink. A master is to tell everybody that he will open this bottle on a very special occasion next time. In a very ideal case, everybody would understand his position.
In some cases it is allowed to deny receiving some gifts. It is possible if a gift is too expensive and too personal, even intimate. Best variant is to express it at the proper time and in person, explaining all the reasons why you can not accept this thing. By the way, it does not mean breaking a relationship and stopping friendship.
And at the very end last piece of advice left – give presents for every occasion, small of big, expensive or not, sudden or long expected, wrapped or not, for women and men, for children and old people, for your dearest or total strangers and tell warm words.
Wow, perhaps that is all. Oh no! Once more - smiling! It does not only prolong a life, but also makes your dearest and nearest satisfied and happy.
