A: Hi, Tom. This is Hannah calling.
B: Hi, Hannah. What's up?
A: I think my garbage disposal kicked the bucket.
B: Is it dying, or is it dead?
A: Turning on the switch is the same as not turning on the switch.
B: Did it make strange sounds before it croaked?
A: Last week I noticed that it sounded strange.
B: You haven't been putting mango or avocado seeds in there, have you?
A: I use the disposal rarely. When I do use it, I put only soft food into it.
B: I think a disposal freezes up when it's not used frequently.
A: You mean it's sort of like use it or lose it?
B: Try loosening it up by using the disposal key.
A: Disposal key? I have a house key and a car key, but no disposal key.
B: Well, I've got an extra key. I'll bring it over.
A: Okay, Come on over, and show me how to fix this thing.
B: Sometimes the key works, sometimes it doesn't. I still might have to call a plumber.
A: Well, there's no big hurry, as far as I am concerned.
B: If we don't fix it sometime, your apartment might start to attract bugs or rodents.
