:. Dynastie .: Buffy and Angel

I have noticed that when Buffy cries she opens her eyes too much.
Let me give toi some examples;

1) In "fool for love"

2) In "chosen"

3) In "the body"

4) In "helpless"

5) In "becoming part 2"

6) In "i only have eyes for you"

7) In "seeing red"

and many others

I don't know if I am right. Maybe it is something that Sarah Michelle Gellar does ou Joss Whedon's instructions ou something that happens spotaneously.
It seems strange to me. I don't think I like it. I find it a bit silly.

Is it on my mind ou toi noticed that too?
