An Interesting Person

I just decided that one of my new subjects for observation in life will be the study of what makes a person interesting. Initially to me, as it is the easiest one to figure out, but then for others also. So off of the top of my head, here are some things that make people interesting:

• The first impression, consisting mostly of looks
• Whether laughs are at the right jokes including yours
• A unique and different life experience from yours
• Clothes that appeal to your taste
• Finding the same types of situations ironically funny
• A talent which could be musical, artistic, spoken, sport-related, etc.

What is it about people that you find interesting? That separates the ones you want to know more about from the ones you don't?
