User and friends database structure

Hi all

I've got the following problem in my database structure : I have a
table "User". Each user can have one or more friends which are users
too. And I have no idea about the way I must think my structure. My
first idea was to create a second table "User2" which would be an
exact copy of the table "User", but I can't because of the fact that
an user can have several friends...

The best way would be to store friends in a collection, and store this
collection in a field of the table "User". But I have no idea about
the way to do that (if it's possible).

So, do you have another solution ?

Thanks in advance

Put all the users (including friends) into one table.

The way to link them depends on the kinds of relationships that exist
between them. If they are directional relationships (User 1 has user 2 as a
friend, but that does not imply that user 2 has user 1 as a friend), the 2nd
table would have these fields:
UserID Number relates to the primary key of tblUser
FriendID Number relates to the primary key of tblUser

The combination of the 2 fields together would be primary key in this 2nd
table.
