Excuse me, can you look for person who agrees to reply for call without foretelling ? I doubt that Real person: man or woman will be agree with this proposition. I got many callings without foretelling. After this I finished any contacts, any conversation with men who called me in this case. As for me it is lack of respecting for person whom you called. We all have our private life, work and our businesses and can't have conversation in any moment when anyone wants to reach us. It is very irritating me when man began to call to me when I am busy. But not only me, other people have the same reaction for sudden calling.
