If I made a single grammatical error than by all means, point it out
Okey doke, in the absence of Delph, I'm happy to volunteer for that task. Remember you asked for this:
I recently did Europe vacation,
We don't 'do vacation'.
I spend a few days in Krakow and Wroclaw
Present tense instead of past. Possible typo.
I just thought Poland was a bit smelly and superstitiuos is all.
Incorrect use of the word 'superstitious'. Also incorrect spelling but we'll let that go.
shouldn't you adapt English ways and manners?
We don't adapt manners. We adopt
we have plenty of native speakers perfectly incapable of stringing together a proper sentence.
Should you find me in that group of people than consider my offer.
Well as you've demonstrated, you are in that group of people. What is the offer exactly? I'm not clear on that.
By the way I very generously left out some of the common American usages which would be considered incorrect grammar such as 'acting defensive' instead of acting 'defensively'.
