I think she is quite shy. When she won Hobart, she looked very nervous and unsure what to do during the trophy presentation etc. I am sure she will come out of her shell more in the future.She is a tennis player not an actress. I think most the young players tend to forget that. Then, they cannot handle the pressure of exposing her private life or their opinions about every single matter.
A good player with a low profile is a breath of fresh air to me. I hope Elena keeps this way and improving her tennis.
