All right ! Yes that clears it up. I was completely wrong... Thanks to you, i can improve my English.
Daneel Olivaw is a character created by Isaac Asimov in his Fondation series. They are (😎) a robot about 20000 years old... That's why i thought of them when you wrote "Erin had to be very old !".
In fact, in Fondation, daneel is clearly identified as a male, so we can say "he".
And finally, i am also a male. I should write my "introduceyourself"...
Thanks a lot for your explanations :-)
