They know that and they have google.
They either don't care or know I don't care in what language you thank me or appreciate my art.
So don't mind correcting anyone, I've been around long enough for people to know my nationality and I am old enough to not give two craps about that.
I would prefer people pass more time appreciating my work and helping me spreading it around or buying stuff I do than googling how to say things in my native language.
That said go buy Elephantmen #70 and #71, 'Cause daddy needs more work.
