He might be imagining you making him a sandwich, its really difficult to guess based on that information
He is stupified with lust. --- or he is just thinking about something else and happens to be looking that way. ;)
it could mean he is shy and love you
It does not necessarily mean anything - he may not be interested in your smiling.
By asking him.
If the guy next to you stares into your eyes without breaking contact or smiling, he might be hypnotized by the color of your eyes. Alternately, you may have something on your face that he is focusing on or he may even be looking at something over your shoulder.
well it could mean he likes you but is a bit shy or he could just be thinking of something someone said if you know him ask him why he won't stop smiling.
Usually when you catch a guy looking at you and smiling it's because he might like you!! If he's a shy guy, then he might be too scared/nervous to talk to you and sticks to smiling and looking your way. If you have the courage go and talk to him!! :) if not, then you can make a friend introduce you guys! Good luck!
Have you tried smiling back at him? Try it, you'll see that if he smiles back, it's a good sigh!
The guy will be sweating and he will be smiling nervously!
You could try smiling at him next time you catch him looking at you he may want to get to know you and not know how to start talking to you
One thing I do is stare(not in a creepy way) at the guy I like then I smile and look away when he looks at me. Also, instead of smiling you could bite your lip and look down. Brush against him "accidentally" Play with your hair and look at him over your shoulder
yes it is
