[CentOS] /proc process information on centos 4.1

I did something simple; on one window did more/etc/mail/sendmail.cf
on another window did lsof -o -b -p XXX -w 
where XXX is hte process number and the SIZE column does not change to OFFSET!
the size reflects the size of sendmail.cf - I was hoping the "-o" would change 
the SIZE column to OFFSET column and show at what offset the program has read into the file?

AM I doing something wrong?

THanks so much.

/man lsof   <- for the list of files opened by a program
man strace <- to take a peak at what the program is doing

Have a nice day everyone,
