How to have fun when no one will play with you:
Step 1: Find cat. Oh there she is ... remember? You dumped all your toys out of the bucket and the cat took the bait.
Step 2: Take cat out of toy bucket and sit in it yourself. Start giggling because this is fun and guess who will come over to see what you're doing? Yup, the good ol' dog, she doesn't want to be left out of the fun.
Step 3: Pretend not to notice that your playmates are not getting along. Well it's not the dog's fault. She really wants to play. The cat just doesn't play fair. Well what do you expect? You took her bucket away from her!
Step 4: Run off and find a brother or sister to play with instead and leave the poor dog to hide in shame under the coffee table after being humiliated by a cat!
