Someone is CRACKERS for crackers...

Alan and I rue the day the sign for crackers was introduced. Crackers, crackers, crackers! Everyday, sometimes every hour, we get asked for crackers. And it's not like she just gives the sign for crackers. She makes sentences: Sign for 'more', followed by the sign for 'crackers' and finally the sign for 'please'. How can you say you say 'no' when she is being so polite?!?!? Sometimes we pretend we don't know what 'someone' is saying. It doesn't work. We are then promptly led to the pantry. Well, the girl knows what she wants.
