Nah, rather about me (sloppiness + using English only from time to time) and (this is big for grammar/style) that my native language is quite far from English in terms of lexical distance, and this creates a lot of problems when your brain (thinking in native language) translates word-by-word to other language.

Especially that I said 'better' not best/perfect etc. As someone commented, SR is not really good for grammar.

But thanks for spotting my mistakes :)
