Hi=) What's the difference?)

Hi! I'm am from Russia.  I am trying  to learn English.  It's so difficult.  languadge(((Can you please explain to me, what's is the difference between "my friends" and "friends of mine".=)

First of all, I treat all essays as more formal than comments or email.  Hence I corrected it as such.

The meaning of the two terms are the SAME. "My friends" is a simple direct sentence.  "Friends of mine" is a bit more long winded.  The longer form, sounds warmer and more friendly.  This is usually the case when compared to short, terse forms.  This especially so in writing because body language and the tones of how it was said are lacking.

"My cat is annoying me".  Just a simple statement and the emotion conveyed is in the word "annoying" which has a bad connotation.

"This cat of mine is annoying me." 

Now there's warmth attached to the sentence.  It means that although the cat is a annoyance, you still love it and that the annoyance is really something you wanted.
