It's clear that women only 'talk' to people they like. Same goes to the men. Similarly, when it concerns someone we like, or a crush. Even if the other person doesn't really show interest, we tend to hope for more. Likewise, when we don't show interest but the other still lingers, we notice that they are attracted to us. Attraction or being attracted to someone means having interest. Having interest in someone whether it is replied may or may not spark feelings and expression. Thus, the law of attraction?
"Is everything really the way it seems?
Is everything alright?
We ain't psychics.
We ain't superhuman."
