My Friends birthday

I went to the centre of London to attend my friend birthday.
She is my close Japanese friend, who travelled to Tunisia together. We ate Chinese dishes with other friends who I do not see often.
They are mainly Chinese.
I am not so close to them like my birthday friend is but still I was happy to see them.
I really enjoy the dinner and conversation with them so much that I forgot I had to leave SOHO before eleven to take the last train to my town.
I stayed in café in SOHO with my birthday friend until morning.
At the café, my birthday friend was talked to some man who was a bit rude. We are friendly Japanese and can be happy to be talked as long as a person is not rude and harmful.
When I am with her, I come across this problem sometimes. She attract not only nice men but also a rude men. I really think she should attract only nice men.
To make the rude man away, she pretended crying from being scared and I pretended being angry. Actually, she was not good at acting and the man looked her suspiciously and asked me if she was really crying or not. To hear his doubt comments, she could not help laughing.
