Shopping for mom 2

Brother:  I don't see why I should have to take you to the mall just because you're my little sister. Sister:  Come on, I am asking you. Brother:  Well no! I was planning to play video games all day. Sister:  Come on, won't you please do me a favor and take me the mall. Brother:  No, I don't want to go to the mall today. It is always crowded on the weekend. Sister:  Please! I really need to go to the mall today, it is very important.
