A louis is the kind of guy every girl needs in her life. He falls in love way too easily and never fully gets over the girl he lost. Having a louis as a friend is the most amazing thing that could happen to anyone. Hes smart, shy, funny, cute, a little nerdy (in a good way), and the nicest person ive ever met. Hes kind thoughtful caring and sweet.

If u get lucky enough to have a louis as a friend, dont let him go. Hes extremely easy to upset. Hes been through things you will never understand, no matter how much you try. Comfort him in times of need, and he'll do the same for you. Louis is my best friend, i will never let that change!

Having a louis as a boyfriend is something ive never experienced first hand, but might experience soon. Louis ive known you for so long, and i know you like me more than most guys have, but i dont know if im ready to love again. He left me broken, but i think im falling for u, and i know youll be there to catch me.
L- loving
O- over emotional
U- understanding
I-inteligent
S-special
Louis i love you.
Louis-hey,what r u doing?
Me-nothing ( i really want to tell you all the things that r going wrong in my life but im afraid my honesty will give hints to my actual feelings for you, and u might get some ideas. Because i actually really like u back but cant risk loosing you as a friend, and im secretly afraid others will judge me for liking you)

A big, obnoxious dude who always says what's on his mind. He might be a jerk, but you can count on him to always give you the honest truth. He thinks he's a lot cooler than he actually is, but people are friends with him anyway because they think he's funny.
Dude.. who is that douche over there?

Oh, that's just Louis, man. You get used to him.

Louis de Pointe du Lac...the hauntingly beautiful and tragic friend/lover/apprentice to Lestat de Lioncourt (a.k.a. The Vampire Lestat) of Anne Rice's Vampire chronicles. He may be flawed but we still love him.
"Louis, Louis...still whining after all these years! Have you heard enough of that...I have! I've been listening to it for centuries." - Lestat de Lioncourt, Interview with the Vampire
