As some have already guessed. I do not live in Great Britain but in Germany.
I am a bit paranoid, afraid someone I know might read what I write by coincidence and find out it is me. This is the reason why I nearly never write about personal things on German boards ;) and as a rule do not say where I am from.
Now in Germany it is really unusuall to call a person you do not know very well by their first name and in Austria, where we first met that is even more unusual.
I knew if was very different in the US and now realize that is the case in Great Britain. So in this case, yes writing at a German Board would have been smarter. Maybe I will do this.
Now with friends of the family, people you like, it is usually different. I am a person, who typically is okay with people calling me by my first name or nickname... unless it is him... because he creeps me out.
Calling someone by their maiden name when they are actually married is actually very unusual in Germany and almost never done. When a woman marries she typically adopts her husbands name (very much like in GB I think) and calling her by her maiden name is both insulting to her and the husband.
As for kissing my hand. He does not actually lick it, just hints a kiss. Jucky tasting cream won‘t help.
I know one of my brothers has a strange feeling about him too or had it years ago when he warned me not to be alone with him, because of the way he was looking at me. But not sure how he sees it now and this brother and me are living in different countries. Very tired today. So I hope what I wrote makes sense.
BTW this is one of the most embarrassing things to have ever happened to me... let me please point out English is my third language... after having done a quick reasearch on „gentry“, because I wanted to proof you all wrong, I realized that this is not the word I am searching for and this is really, really embarrassing.
