Elena adds insult to injury
I really think that Elena D. does not like Venus (on a personal level).
The whole "I don't have a LITTLE sister..." comment prob. made VENUS feel like complete trash.
We all remember the "heart-felt" reaction from Venus after Serena won her first SLAM at the USopen. So we know Venus does not like to be reminded of the fact that her sister is 10X better EVERY DAY by a PLAYER she just lost to.
