Both of them. Sometimes people say I look like my mom, but I think they just say that to be nice. I really don't. I have a similar eye color to my mom (both blue, but mine is more on the gray side and hers is more green), and that's basically where the similarities end. I have a nose like my dad's side of the family, wavy hair like them, and my facial structure just looks more like theirs. No one in my family is very tall (my mom is only 5'2, and my dad is 5'10" (and he's the tallest in his entire family!), and I'm only 5'4", but the doctor said I wouldn't get much taller.
But my hair color is kind of inbetween my mom's and my dad's. My mom has extremely light brown hair, and my dad has very, very dark brown hair. Mine is kind of a golden browny color with blonde hair and dark brown hair mixed in. So, yeah, I look like both of them.
