W: Are you all ready for Christmas?
M: Are you kidding? I haven’t even started. I’ve done zero shopping.
W: Well, you’d better get going; Christmas is only a week away.
M: I have to tell you that I’m one of those people who really get stressed out by the Christmas rush.
W: Oh, I’m not. I love the holidays. I love the crowds, the shopping, the lights, the music, the food, the parties, all the presents.
M: That’s just the beginning. My wife always spends too much money on Christmas.[13]The average Christmas expense for US families is about S550. But somehow I always spend about twice that much. It takes me till April to pay off all our Christmas bills.
W: But didn’t you use to love Christmas when you were a kid?
M: I guess so.
W: I know you did. You were the most excited kid in the whole class I remember. Maybe Christmas is for kids, but you can still enjoy it through the eyes of your children.
M: Well,[14]kids enjoy it because they don’t have to do all the shopping and pay all the bills.
W: Maybe that’s true. But for me, Christmas is about what’s in your heart and how you can make others happy.
M: You’re right, Mary. I’m going to try hard to keep the true spirit of Christmas in my heart.
W: I’m glad to hear that John. By the way, do you have your tree up?
M: Oh,[15]I hate all the needles that get all over your living room floor. I mean, we’re going to get a decorated tree today.
W: That’s OK. Just enjoy your holiday.
