Yeah, you Russians are funny that way.
I have had friends and family stay over when they have been visiting. Not so many, and I like to keep it that way. Though the only time I was really not enjoying it was when a friend made me host his twenty year old son whom I had seen last time some 17 years ago. Meanwhile he had grown to two meters and let his blonde hair reach his shoulders. Of course he also has blue eyes and was a semi-professional athlete.
He spend a total of 30 days with me. And bedded around 40 different girls during that time; the first night was the only time he came back alone.
