And everytime he sees me he he starts singing " I could be chasing but my time would be wasted they got nothin on you" and I look at him like waa? lol and I smile. Last night I saw him and he walked by me and he sang the same like and he touched my face. then, he went over to my friend lets call her sam, and touched her shoulder and said they got nothin on you and then the walked away. Then, I was getting my stuff and the night b4 I posted something on fb about how one day I was going to be a billionaire one day and that I was tired of ppl telling me I couldn't follow my dreams and that one day they will see me whereever they go I suppose idk. it was werid and out of anger what I posted. And, I was walking by him and he said something in spainsh real loud and then he said that girl is gonna be a billionaire or something like that. then , I was outside with his sister cause we are pretty good friends and he said see ya later girl and he touched my shoulder. and, my dad came and picked me up. and he said by. And then he got on his bike and he started riding it without any hands in front of us. and my dad was like who is that ? was that ur friend and i'm like yea thats him and his sister. lol. thank you for you time, and your answers.
