Is it true a girl who tucks her hair behind her ear, is subconsciously attracted to you?

Is it? I was standing near a girl and I lent down to do something and I could see her tuck her hair behind her ear.
Someone later said that that's body language for attraction? I've never really even taken notice of things like that, do you think it's true?
