Question

能不能帮忙改下语法错误

I knocked softly. A red-headed tall woman open the door. I know she is Eugene’s mother.
“ What do you want?” Her voice was prosaic but she sized me up disdainfully.
“ I’m Eugene’s friend. We agreed to study for an American history test.” I pull out my study source on purposely to show that I sincere desire to study with Eugene.
“ You live in El building?” Her tone sound like there’s more in that than meet the eyes.
“ Yes.” I said
She consider for a while and said “ Okay, come in.”
