Dear Human, You are very lucky. You have many types of feelings, and there are many ways to show your feelings. If you're in the mood for something, others will look pretty clear. In fact, if you're having mood swings or going through a painful breakup, you can't hide your emotions. I am a cat, so I am not very lucky. I have no way to express my feelings. I couldn't smile or look sad, or laugh or cry. Well, I have many, many emotions. I deeply felt sadness when the boss didn't feed me on time. I saw jealous when the owner fed the dog on time, not for me. I was confused when the master forgot to let me eat, or when he forgot the dark pamper. That really hurt my feelings. Sometimes, I see homesick when I think about the woods. I have a feeling I need to explore my wild instincts. Staying in the house for so long made me dull. But I'm not too moody. Or too serious. In fact, I feel grateful for a lot of things. Like when master leaves me alone when I'm sleeping. or when you forgot that dog outside. Anyway. As a cat, I have no way of expressing my mood. My face is always the same, no matter how strong my emotions are, whether I'm happy or depressed. It is just inert. So, I use other ways to show you my feelings. I bring you rats to die when I'm happy. I peed on your shoes when you piss me off. If I scratch your home furniture, it means it's ugly. Love, Your cat. DỊCH ĐÚNG MÌNH SẼ VOTE 5 SAO + CẢM ƠN
