Here's a hypothetical question.

It's easy to select a layer, create a buffer around it's features and =
select
the information from other layers that intersects or falls completely =
within
that buffer (you can use Select by Location, Edit Toolbar or the Buffer
Wizard).

But how about buffering a layer within itself?

Confused?  Here's an example of what I am looking for (purely =
theoretical).

Suppose I have a shapefile with points representing all the 100 Fire =
Stations
in a major city.  The city manager wants to know which Fire Stations are
within 2 miles of another Fire Station, with the thought that some of =
these
redundant stations could be closed and the resources better utilized.  =
How do
I create a buffer that would show this? or is using buffers even the =
right
way to go about it?  Keep in mind that I am not a programmer, so I'm not
looking for a complicated script or Python program to do this.  I'm =
primarily
looking for interactive ways of doing this with built-in ArcView/ArcInfo
tools/commands.

Suggestions are appreciated and, trust me, no Fire Stations are actually
subject to closure, I just thought that it was a good example.
