    Hi artist fun
    Keep writing the guy you like go girl. That is how I met my girlfriend I wrote her notes from her secret admirer. We have been together for five years I’m sixteen and we are thinking of getting married in two years or even sooner I met my first girlfriend by getting my friend to ask her if she likes me and she said she did. I love how we have a community in the comment section and that we can just share stuff like that. to alblack: you are the best you support everybody

    AWESOME PODCAST! ⭐️⭐️⭐️⭐️⭐️
    I have listened to this podcast since I was about 4.It’s still great! Here are some of my questions: Where do fish go in the winter when the ice is frozen? Would it be possible for people to live to 1000? 2000? Could someone live on the moon? How big is the universe? I have trillions of questions swirling around my head. If I could I would give you this many stars: ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️! Great podcast 🤣😍😊🥰😁😉😅😀🤪☺️🤗😜🙂😎😆😏🥳😄😃🙃😋😌🤩🤭😝😇😛😈😹😚🤓😻this doesn’t even begin to express how much I love this pod!!!!!!!!!!!!!

  • The first time you were there.
    The first podcast ever
    The union said the strike would not be affected because the strike would have to end in March and the union said the union was prepared for the strikes if it was not to meet the union deadline and would be prepared for a new contract by mid March to protest a no vote in a new labor dispute that could lead the strike in March or March to the strike in Chicago or Chicago next month to end
  • Clara ❤️♥️
    Love the podcast!
    Negative: I love this podcast but I’m not sure everything is true for example: l don’t think that your pupils are actually holes in your eyes. I still love the podcast but I think you should put a little more effort in to the fact checking. Positive: I love the mystery sounds and I love the hard ones. I have a question: why do whales have are holes? I like the podcast and want you to doing it! -Clara

    MY FAV
    I am a HUGE fan of Brains on! I’ve been listening in for 3 years now and I love listening to you guys. What I like about this podcast is how most episodes can connect to me and others. I can also learn about something I’ve never known of before. I would like an episode on OCD. I do know there was one on ADHD but I would like one for OCD too. Thank you so much for reading 😘😘😘😘💖
