It's a normal day. You go to school as usual and walk into class and sit down. You see, me walk in. I'm pretty popular because I'm funny and like helping everyone, plus I'm bubbly and always like to annoy you. I walk to you and look up at you. You look nice today I smile cheekily and sit on your lap. You try to tell me to get off, but I get comfortable on you. I feel something and laugh whilst blushing a bit. What is that?
