Perfect gifts
There are a lot of gifts people like to give that show someone that you care about the details. Someone who attends a lot of black tie dinners may be a collector of great cufflinks and thus noticing his or her wearing several different sets may give you a clue. You can always tell them how much you like their cuff-links and gauge their reaction to it. If they have a story to tell then you know they are a collector and sentimental too! You can get cuff-links online and there are plenty of gorgeous ones to choose from. If your friend is a big superman fan they have that too! Personally I love the superman logo as it reminds me that although I am but a mortal, I am secretively superman in my ambitions to succeed in life and get ahead!
