When a guy stares but doesn’t smile, you may remind him of someone.
Oftentimes, when we are reminded of someone, we may be lost in our own thoughts for a moment.
This may be the reason why he isn’t smiling as he is staring at you. He may be lost in thought.
He may be replaying in his head the times and experiences that he had with the person that you remind him of.
These times and experiences may be good or bad.
He may be literally caught in a moment of nostalgia and may not even be entirely aware of the effect that he may be having on you.
When a guy does this, he may put himself in a good mood or bad.
However, this typically isn’t dependent on you personally.
He doesn’t know you all that well if at all.
His reaction is typically borne of whatever emotion the memory that you trigger has on him.
It can be that powerful of an effect.
This is one reason why a guy would stare at you and not smile.
Another reason may be because he is shy.
There are shy guys out there who have very little experience with girls.
They don’t quite know how to show a girl that they are interested.
They may also know that the chances of them talking to said girl is so slim that they aren’t even keen on smiling.
They just don’t know how nor do they have the confidence to express themselves to this girl.
A part of them may feel like the girl may already be taken.
They then simply stare at the girl and not smile because they assume that they wouldn’t be able to get the girl anyway.
These shy guys may even begin to wonder if they would stand a chance with this girl if the girl were indeed single.
As they are lost in thought, they don’t smile.
They don’t want to show the girl that they may like them by smiling at them because they don’t want to be at the receiving end of rejection.
Shy guys often think in this way.
Shy guys tend to be terrified of rejection.
Perhaps, he has had some negative experiences with girls in the past.
As a direct result of this, he doesn’t smile because he wants to ensure that he doesn’t give away any signs of interest.
He doesn’t want to be vulnerable.
He doesn’t want to feel the sting of a girl who doesn’t return his stare or smile back at him.
On the flip side, he may even want the girl to smile at him but feels that by not smiling himself, he shows the girl that he doesn’t care either way.
It’s almost like a defense mechanism.
Another reason why a guy would stare and not smile at you may be because he is playing a game of chicken and gets off on the power.
Yeah, there are some guys who actually enjoy the sense of power they get when they make someone uneasy by staring at them without smiling.
Guys who do this to simply make the girl feel uneasy may be doing it based on negative experiences that they have had with past girlfriends or girls in general.
They may want a way to assert themselves.
When they sense how the girl is becoming uneasy based on their staring without smiling, they may feel like their job has been done.
They gain a sense of satisfaction that they have asserted themselves and move on to the next unlucky girl who happens to catch their eye.
