Birdie was kind of a little bitch.
On the surface, she seemed to be (and was prob'ly intended to be) a very endearing character. But with frequent viewings, you can also see she was kind of a kook and VERY condescending. Everything was "deary this" and "deary that" and "ask me for money because I'm very rich." But the worst was her "cest la vie" attitude when watching Kathleen worry about her crumbling business. When Kathleen is desperately looking for answers, Birdie was a little snide about it. "Oh Birdie, what would mom have done?" "Well lets ask her, shall we?" And every time she looked at Kathleen, she had this "girrrl, you goin' DOWN" look on her face.
I didn't know whether to love her or hate her.
