When a guy tells you that, it could mean a lot. 1, He likes you. 2.He's being nice. 3.He's interested. 4.He's bored. 5.He wants a conversation.
As much as I'd like to cut right to the chase and give you a direct answer, I feel compelled to at least give you a quick warning about complimenting coworkers you may have romantic feelings toward....
exactly that. "youre a great person"
Make it, because most big companies probably don't care.
your girlfriend or boyfriend will tell you ;)
