Do u like it when we look?

Ok this goes out to all guys out there, so if u remember any old questions of mine. im the country girl that is frustrated with the lack of hard workin/country/constructiony kind of guys out there. anyway . in the mall that i work at theres this awesome construction worker doing reno's and i kind of look at him often and smile. and he smiles back. but then looks down kind of quick . SO i dont know if guys like it when girls look at them like is it an ego- boost or is it like creepy lol . i kind of think he might just be shy . is that a possibility . but like when he walks by sometimes i see him looking in at me. but then when i look he like looks away super quick ., lol i know this seems very silly but anyone have any ideas/ suggestions
