Jack

Kind and funny. Good-looking, and in love with a Kristen. Always will be, even though they might have a crush on someone else.

Scared of telling someone how they feel, though the person usually feels the same way.

Kid 1: So Kristen and Jack got together.
Kid 2: No duh, they were made for each other.

Jack

Someone who you could never forget, the kindest person who is not afraid to say how he feels. He has the strangest of friends and is very easy to talk to. You should never walk away from a Jack, it is the biggest mistake you could ever make.

"Jack is the sweetest guy!"
"I wish I had a Jack..."
