in that case I have to see it as another attack at me and even wonder about its meaning
... and no it's not pleasant.
Why people like hurting the others like that ? I don't know, is it part of the tennis attitude ? Once, I thought that, yes, but it was disappointing for me, I prefer looking at tennis my own way, it's rather something I use not to be depressed.
Fortunately I don't generally enter the "chats threads" section.
you would have to be weak of heart to see it as an attack... however, i have a feeling you are french, and so, you are forgiven...
