I am really tired of unreliable exchange partner. First of all, I can not understand why people do not communicate with. In order to initiate the exchange, should agree before exchange all the details.
Secondly, I am often meeting people who offer themselves for exchanges, but ethey are thinking too much of them selfs, since they are from "rare" countries. They think that if they are nowhere in Saudi Arabia or morocco or another tip of the world, then they have the right to demand a lot but give little or no give! And if you dare to ask such a pre-agreed rules, in the answers to you insolently, that "what you wanted? I am a uniquely country, you should also be satisfied with an empty envelope."
Or, if agreed upon that both partners will send the registered letters at the same time, but after, it appears that this second "uniquely" country, however, decided to wait until receive your letter, and after that maybe you will receive answer. Finally, you spend a fair amount of money and time and your nerves, and if you still get letter to the end, the more it does not offer joy.
I'm really tired of these partners. maybe i should to made black list of my own experience, that someone else would not have fallen into the trap of the same.
