Needed place for kids to sleep while visiting grandma and now they argue over who gets to sleep on the air mattress. Both think it's more comfy than their bed at home.Would have given 5 stars, but the bag it comes with to put it in is worthless, no chance of ever getting it in there again.

Ex Output:
Positive


Ex Input:
A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.
