It means they are madly in love with you !!! Or they're just friendly ;p
What does it mean every time you see a certain person and they smile and say your name or nick name?
It means that they are not asleep. They have noticed your presence and acknowledged it.
It means they have manners.
OH SNAP!!This person may have manners.
Well, they obviously know you.
Here is something for you to consider...because our Northern European culture tends to be COLD. So, whenever someone expresses their own natural friendliness toward our fellow humankind, it can be misconstrued as a romantic overture.

My suggestion: Just accept the warmth from this person delightfully, and return their smile and greeting. Then, noticing how good it makes you feel, reach out to everyone around you with the same kind of warmth.
*** If there is ever any romantic intention, let it develop on its own, with very clear signals.
it means they want u for a one night dance
Not sure are you two close friends?
They like you.
