Derek is clever, funny, self-effacing, adorable, witty, nasty, and very, very endearing. Not only that, he is a great writer.
There is something chemical that happens when Derek is around people; his enthusiasm, his ability to raise the temperature in any situation, seems to make everyone more fun, more amusing than they might be without him there.
He is to parties what rob pattinson is to vampires. but you don’t get bitten, you get smitten.
