Uhhh saying "me and my friends" is not standard English in this case, it is grammatically wrong. You have to say "My friends and I will go to the mall". Even natives have trouble knowing when to use it correctly.

Just to add to what いさむ said, *poorly-educated* natives (and people who don't care) have trouble with it. It's simpler to remember if you just think politely by putting the other person first and then the "I" ( "__ and I")...

Here's another clue about using "my friends" "me" and "I" Split the noun and pronoun into two sentences, as follows: My friends will go to the mall. OK I will go to the mall. OK Me will go to the mall. NOT OK Another explanation follows: My friends will go to the mall and I will go to the mall. (one sentence made up of two clauses joined by the conjunction "and"). My friends and I will go to the mall. One shorter sentence using the conjunction "and" to join the two subjects, "my friends" and "I", to form one sentence.

Hi, When making a list of people, it's considered proper to put yourself at the end. Politeness, I suppose. So "you and me", "my friends and I", "my brother, our father and I", etc. As for using I/me, Richard's given a great way of working out which is correct. :) For the grammatical nuts-and-bolts, use "I" for when you are the subject, and "me" for when you are the object. I will go to the mall. (subject!) My friends at the mall will meet me. (object!) Native speakers may sometimes speak their own language sloppily, so it's a good habit to remember what you hear may not always be "correct", or even good.

Now, why didn't I think of that? Peachy's answer is grammatically absolutely correct, totally right, bang-on (slang), and right-on (slang). Only a linguistics teacher would think of answering a grammtical question with a grammatical answer, while the rest of us struggle to answer in our near-comical, roundabout, and dare I say ass-backwards humble way:) :) Thanks to Peachy for reminding me that grammar rules exist for a reason.
