Son:Mom, I picked a cat on my way home. Can I keep it in my restroom?

Mom:Oh, you should not keep pet in your restroom! Especially, it's such an ugly and dirty cat! Take it out and never keep it again! OK?

Son:Wow, mum, please! Cat is my favorite animal. It's so pretty and interesting! At the same time, your dog pet is lonely, isn't it? The cat can make friend with you dog.

Mom:But, the cat is too dirty. It may be bad for your health! Don't you know？

Son:Mum! Please! I will tidy it up. And I will take it to the pet hospital for vaccine( 疫苗 ).

Mom:Ah, Ok. It sounds reasonable. So take care of it carefully.

Son:Mum, you are so kind. Thank you very much.
