Hilary Duff can't take two seconds to sign a piece of paper?

Last week in Texas, Hilary was spending some time with her family at a local Oyster Bar when two 9 year old girls heard that she was there. They immediatley came up to the Oyster Bar with posters of the pop-singer. When asked if she would sign the autographs she said:
'I don't really get to spend a lot of time with my family; sorry' and walked out the door.
Apparently though the manager of the Oyster Bar asked Hilary before she left to sign a menu for his younger daughter and she did.
So I ask why she couldn't take two fucking seconds out of her busy day being a pop-star/actress to sign two little girls posters. Seriously...Maybe the weight of all her ghetto jewelry was getting to her......
