I have 2 daughters, 17 and 13. My 13 year old is quiet, shy, and just plain tough. She has always been tough. She carries boxes and stuff that my wife and her older sister can't. If she socks you in the arm, it's going to hurt. Over the years I have joked that she better marry a Linebacker because she will beat the crap out of most anyone else. When she was 2 I could tell her to tackle her 10 year old male cousin and she could take him to the ground. She has a nickname in our family, Silent But Violent. She's not big. I imagine she will be about the same size as my wife at best. That's about 5'6". Right now she may be 5'3". Yesterday at her Junior High School a boy made a comment and she called him a wimp. He responded to this and she challenged him to arm wrestle her. He accepted and she promptly stomped his butt. Right in front of the whole school at lunch time. I pity the first boy who breaks her heart. She is going to hurt him.
