I responsibly say that it's false!
Maybe we don't show our feelings to much on public, but when we are alone in a private place we are the hottest on Earth. We open up and give everything we have, all our love and passion. We know how to set up fire between two persons. In love, we are much more dedicated than anyone else. We can fight for love till the last breath. We never give up!
We put the spiritual above the material. We know how hard is to find a true love and we always worship it.
Whoever reads this... If one day you find a russian partner, hug him and never let him go!
