She should have been pleasuring herself most of the time
If she fancied her young self that much to form a relationship with herself, the younger self should have spent most of her time masturbating in the mirror.
Younger self seemed to have too much self-loathing considering older self thinks younger self is really hot. Younger self probably should have had more confidence than she did.
Also, older self is so determined to kill 'the man' who got her pregnant and disappeared, but when it comes to the scene when older self travels back in time and meets younger self, it's like it doesn't dawn on older self that she/he is that man at that specific moment. I thought there'd be more of a "Holy *beep* It was me!" expression on older self's face at the realisation.
