I think that it has to do with being nervous, ill-at-ease
and afraid of accidentally making a social blunder and embarrassing themselves.
Not long ago, I made a joke with someone
and it turned out that he felt bad and got mad at me. I did not expect that. U never know.
Fear can make people stiff and awkward
can screw u up.
In due course, maybe u 'll learn about psychological "approach-avoidance reactions."
I suggest that u write it off to a human failing like bad breath.
That 's how people are wired up inside, emotionally.
Most Respectfully, I suggest that u and your family
try to be as happy as u believe that Lilia wanted and wants u to be.
I hope that u will remain with us as a member of the forum.
U seem like a really nice girl, and we 'd all really enjoy your cyber-company.
