French people

I've recently found out something .. lol
One of my friend was writing something in English, writing her thoughts (about her relationship with her bf)..
Anyway, she showed me and I told her that she's done some mistakes.. I know my English isn't perfect and all but this was full mistakes such as "you is.." or "He tryed.." stuff like that you know..
I took my lead pencil and corrected the mistakes .. to help her out .. and she kinda went mad at me saying that I have no clues about the English language that I should better go back to school to learn it and all .. THAT was shocking lol .. I mean .. I correct her mistakes .. and she puts them back because I suck in English... I was speechless, honestly!
Anyway, just had a whole week of holidays.. and still not enough ! :-(
Everyone is having 2 weeks, but we, at uni, we only have a single week ! what a shaaame lol
Back to uni on Monday .. oh well... "life goes on"
Cheers
