Really guys, thank you for your support. I feel better now
I guess it is something foreigners feel when they practice another language. I think they get the impression that it either should be done perfectly or not done at all, which prevents embarrassment successfully. But really, some mistakes are really embarrassing, specially mistakes in semantics. And sometimes I pause long that it feels awkward
شكراً جزيلاً يا أعزائي
That was Arabic for "thank you very much, dear all"
