They could like you and want to get you know you. Sometimes they just look at you with a flirty smile cause they are a player and may be doing it to get your attention or be playing with you.
it depends if the smile hes giving you is a friendly smile or a flirty smile.
Do you like him? If you din't then just pretend you didn't notice. If you do, then turn look into his eyes give a flirty smile and then look away.
Flirt, stare at him, smile, be funny. Be promiscuous... give him a look (flirty like lock eyes) then immediately turn away. It makes guys want you more.
it means he totally likes you and is trying to flirt!
Its because they know about your crush
Smile at him and say,"You're cute" in a flirty, mysterious way.
The same way that you would attract any other guy. Be yourself, get him to notice you, flash a smile, talk to him, be funny, be flirty.
guys like personality and looks. make your personality stonning and a guy might like you. try sports!
he probably likes you!
be yourself
They don't. It's just that some straight men perceive flirty signals everywhere they look.
