A nice guy who loves a good joke, isn't disrespectful to others, hates bad words, and has millions of friends. Traditionally an actor/writer/dreamer with brownish red hair. Fun to be around, sometimes annoying but often quite awesome. Trust worthy but can't keep a secret.
Neil is awesome, I can trust him with anything and I would hate to lose our friendship!
