Don't start a dialogue "hi,how are u?where are u from? what's your name?"
And never "do u have skype/instagram/whatsapp/facebook? and so on..."
It's very corny. don't waste your and my time. be original. in the world there are many topics for conversation.
If u learn russian language,or are u just interested about my great country, then i'll help u. don't be shy:)
