W: Dave. I’m going to the supermarket to pick up food and drink for Saturday’s picnic later. Any suggestions?
M: Well, everyone has been talking about having a barbecue down by the river, so why don’t you pick up some ham burger and hot dogs?
W: Okay. And you better pick up some chicken for those who don’t like hamburger or hot dogs.
M: Alright. What else? Uh, we’re gonna need some soft drinks, How about ten of those big 2-liter bottles?
W: Sounds fine, but be sure to buy a variety of drinks.
M: Okay. And what about dessert?
W: Well, maybe we could ask Kathy to make a few cherry pies like she did last time.
M: Well, I wouldn’t mind that, but you know, she’s been very busy working two jobs, so I’d hate to ask her, and uh... why don’t you whip up some of your oatmeal cookies? Hey, you could even ask, uh... ,what’s her name... yeah that new girl, Susan, the one that moved in across the street! I bet she’d be willing to help you! She’s a real knockout !
W: Nah, I don’t think I could ask her... I don’t know her phone number, plus...
[Door bell tings...]
M: Hey, you don’t need to. She’s at the door!
