Me...

I had to write a letter, like a presentation.
I don't have a perfect english so I asked to Mr. Justin (A guy from Chicago who works in my school) if he can help me and...

"... but also I'm a perfectionist person and sometimes I criticize, that's why sometimes unfortunately I get angry with other people..."

He added the word "unfortunately". I'm sorry, but I don't feel bad when I get angry with the people Justin :P
