My friend's friends' brothers might be more of interest to me since I'm a woman.
Well, sorry, how should I know.
But krozet is right.
These days what I think is normal and what I think is abnormal just does not fit in the PC of the present world.
Thanks for your advice everyone. I think I'll suggest that my friend stay ashore when his "friends" are visiting. We'll see how it goes. After a couple of weeks with him aboard, I'll probably be ready for a break anyway.
