 tilde + variable expansion in bash

I'm having an awful time getting something to work in bash. I want to
find the
home directory of a user ... no big deal?

Simply using ~ doesn't work since the user is not running the shell. And
since I
don't know the name of the user, I can't do something like ~bob/...

However, the name of the user is set in a shell var. So, I thought that:

        FILE=~$USER/filetoread

would work. It doesn't.

If I were to use

        FILE=~bob/filetoread

bash looks in the password file and finds the home directory for user
bob. However,
when using ~$USER it doesn't work. $FILE ends us as ~bob/filetoread, and
the tilde
subsitution is not done a 2nd time...so a file by the name
~bob/filetoread is looked for,
not /home/bob/filetoread.

I think that it is just a matter of bash doing what it says it does in
the manual. First tilde expansion is done, and since what follows the
tilde isn't a username, it is left as is. Later the variable is
substituded, but that doesn't help then.

So, is there a way around this????
