　　Mina is exploring a night market with her friend Sam.

　　S:I've got to have one of those cute puppies!

　　M:Sam, what are you thinking? You should never buy a puppy on impulse.

　　S:I'm not: I've always wanted a dog. Besides, they're Labradors, and Labradors are really fashionable right now.

　　M:I can't believe what I'm hearing. Pets aren't fashion accessories!

　　S:Oh, come on! There's no harm in choosing a puppy because of its looks.

　　M:Try telling that to the scores of would-be-loyal dalmations that ended up getting dumped on streets.

　　S:Ouch! Good point. Parents bought them for their kids because of the movie, right? But without considering the demands of dog ownership.

　　M:Exactly. And, along with thousands of other dogs that deserve a home, they're now condemned to trying to survive on the streets.

　　S:I know that usually means suffering disease, hunger, and an early death.

　　M:It's an appalling situation. And if I told you what happens when they're taken to the dog pound, you'd be horrified.

　　S:OK. OK. You're convinced me: Buying a puppy on the spur of the moment would be a dumb thing to do.
