5'7" (somedays I get up to 5'8", but I never know when that'll happen

)
I'm taller than my mom (who's 5'5" or so), but much shorter than my dad (who's 6'1" or so), yet I'm also taller than my step-dad (who's usually about 5'6" or so). So in family pictures, it depends on who I'm taking a picture with as to where I stand
