Hi everyone,

Could you please proofread my paragraph??

My Wonderful Sister

I think my sister Hannah is amazing. First of all, she is very practical and down-to-earth, so she always gives me good advices and I can trust what she says. Hannah is totally reliable, too. For example, if my mother is out of the house, Hannah knows how to act as if she were my mother. Therefore, she is my mother's right hand. In addition, she is extremely generous. She is always doing things for other people. Another great thing about Hannah is that she is very funny. She knows how to make me laugh. She is the best sister in the whole world
