Why do older men stare at me?

Anonymous
This is a strange question but I've noticed a few times I'll be out shopping or something and I'll look up and there will be an older man (usually 30-60) that has been staring at me and they will give me this creepy smile. It really confuses me because I always wonder if they think I'm weird or pretty or what. Have any girls had this experience? Or any older guys? It makes me very uncomfortable because it's not like a flirty glance but something much creepier. I'm 19 by the way.
