Come in and have some coffee , Anna . The kids have just gone out to the mall to hang out with their friends .   I saw a lot of teenagers when Alan and I were there yesterday .   They spend hours there , especially on weekends .   Speaking of that trip , Alan bought a shirt at a department store , but the sleeves are too long . Do you know a seamstress or tailor who can shorten them ?   I know several . But wouldn't it be easier to take the shirt back and exchange it for the right size ?   Isn't that complicated ?   No , it's easy . We'll just take the shirt back to the men ’ s department and show them the sales slip . They'll exchange it for the correct size or give you a refund .   We ? Do you want to go with me ?   Sure . I love going to the mall .
