Daniel , you can't spit the gum everywhere .   Come on , just a little piece .   Do you know how many people chew gum everyday ?   I have no idea .   Just in Beijing , people consume 300,000 pieces of gum every day .   That's amazing .   If all the people spit out the gum like you , the whole world would become a big trash can .   Come on , you are making too big deal out of this .   I just want to remind you to behave yourself .   OK , dear sister , I see . This kind of thing will not happen again .
