Having a crush every now and then is as normal as craving for shopping… but acting “normal” with your crush is normally quite difficult!
You would also not want your actions and behaviour to shout out your feelings to the guy every time!
At the same time what fun is a crush if he doesn’t respond to your feelings?
So, the idea is to make HIM interested in you, without YOU seeming to be falling for him! This could be difficult, because every glance from him will make your heart race towards him. This, you need to hold, and instead get HIS heart racing towards you.
