  Easily, any file under "your" directory - regardless of ownership or mode, 
can be "deleted" by "you" - all you have to do is say "yes" (y) to the 
question that pops up asking if you are "sure"....  Nature of "*nix" systems.

EXAMPLE from an RAQ4:

<< first as ROOT create a dummy file in a user space >>
[root web]# touch testfile

<< then login as this "regular" user >>>
<< note prompt>>
[larry2 web]$ ls -l

<< note the file is GONE>>

 As stated before, the ONLY way to ensure the file cannot be removed is with 
the chattr command.
